this:\r\nhttps://github.com/corona-warn-app/cwa-server/blob/3b98beb268bac511c00f8e13bcbb4978a8cdb4fd/services/submission/src/main/java/app/coronawarn/server/services/submission/verification/TanVerifier.java#L102-L115\r\n\r\nThere are a couple of issues I would see here:\r\n1. The tan entity is build from a string which can cause bugs, encoding issues an more.\r\n2. When the interface of the verification server changes (and this a repo owned by the same organization) this has to be modified as well and can cause runtime bugs without proper system testing\r\n\r\n## Suggested Enhancement\r\nI would suggest two things\r\n1. Create a DTO (Pojo) for the tan payload and pass that to the rest template to let Jackson handle serialization\r\n2. If a dependency between cwa projects is \"allowed\" (which I would think is perfectly fine)  I would actually move that entity to the verification server project in a separate maven module. I would add [Spring Feign client ](https://cloud.spring.io/spring-cloud-netflix/multi/multi_spring-cloud-feign.html) and use that in the CWA server. Feign is like the reverse version of `@RestController` and supports the same annotations. It will create the client implementation from the given interface at runtime.\r\n\r\nThe client would look like this:\r\n\r\n```\r\n@FeignClient(name = \"verification-server\", url = \"${services.submission.verification.baseUrl}\")\r\npublic interface StoreClient {\r\n\r\n    @RequestMapping(method = RequestMethod.POST, value = \"${services.submission.verification.path}\", consumes = \"application/json\")\r\n    ValidationResult validateTan(Tan tan); // both classes should be Pojos\r\n}\r\n```\r\n\r\nThe usage would look like this (I did not actually implemented that!):\r\n\r\n```\r\n private boolean verifyWithVerificationService(String tanString) {\r\n   Tan tan = Tan.from(tanString); // This should also do the UUID verification!\r\n    \r\n    ValidationResult result = verificationServer.validateTan(tan);\r\n\r\n    return result != null;\r\n  }\r\n```\r\n\r\n## Expected Benefits\r\n- Compilation breaks when interface changes\r\n- Less risk of bugs\r\n\n", "hints_text": "I like those suggestions. The introduction of a value object for a TAN is something I thought about suggesting as well. Would bind the verification logic into a value and make the using code more expressive and safe.\r\n\r\nAlthough I am more of a hypermedia guy and thus not a big fan of hard coding URIs in clients, I think Feign would be fine here, although I think that \u2013 unless also used in other places \u2013 the benefit of using that over `RestTemplate`/`WebClient` is not that significant.\r\n\r\nWhat I do think needs improvement is the setup of whatever client API is ended up being used. Remote calls definitely need a timeout as otherwise the system is stuck in case the downstream service is not answering at all for whatever reasons.\nAlso, from a security perspective this implementation shall be changed. When building the json string this way, a malicious tan can inject arbitrary fields to the json object. Even if the tan is previously checked for the correct syntax in another method, this implementation is error-prone. The syntax check for the tan can be called directly before creating the json string or the tan can be filtered with an whitelist approach.\r\n\r\nI assume the previously mentioned changes will also tackle the injection issue. \nI haven't really looked at the verification server but calling as POST to verify a TAN seems to me a bit unRESTy to be honest.

We don't want the TAN to come up in any of our infrastructure / http access logs by chance. \r\n\r\nThis does not only apply to TANs but to all other sensitive data we are processing.\nI'm working on a PR.", "created_at": "2020-05-30T17:08:20Z"}

Good point with the UUID type, I'll bring it up in the team discussions and report back. However, please note that, to my knowledge, the type of the diagnosis keys is not explicitly stated as UUID by the Google/Apple spec, but only as \"Data\" (see [here](https://developer.apple.com/documentation/exposurenotification/entemporaryexposurekey/3583679-keydata)) containing 16 bytes (see [here](https://www.blog.google/documents/60/Exposure_Notification_-_Cryptography_Specification_v1.1.pdf)). This can, in theory, be mapped to a UUID, but I would like to investigate if the PG UUID type implies any restrictions. For example, UUIDv4 reserves 6 of the 128 bits for version information, leaving only 122 bits for the payload (see [here](https://en.wikipedia.org/wiki/Universally_unique_identifier#Version_4_(random))) - and this would cause major problems for us.\r\n\r\nRegarding the collisions: we currently also don't see this as a major risk. Our current strategy, as you proposed, is to simply ignore duplicates.\n@pithumke Well, you're the one defining both the client and the server side, the EN API is agnostic to its content to allow that freedom of implementation, so you can define that key to be whatever you want it to be, currently you are validating it as UUID in the server and the test case generates a UUIDv4. the UUID data type follows RFC 4122 as you would expect and would naturally cover UUIDv4. All UUID versions reserve a place for version information. _please_ do not try to come up with your own UUID variant if that is what is suggested here\nHi @oiime, thank you for your comment.\r\n\r\n> Well, you're the one defining both the client and the server side, the EN API is agnostic to its content to allow that freedom of implementation, so you can define that key to be whatever you want it to be\r\n\r\nYes, we do specify and develop both the CWA server and client. However, we neither specify nor develop the on-device APIs - that is done by Apple and Google. Inside those on-device APIs is where the keys are being generated and that does not give us much freedom regarding data types on our end. In the specification it is stated, that the key data consists of 16 bytes (= 128 bits). Since the use of UUID would restrict that to 122 bits, we can not use it as the column type on postgres.\r\n\r\n> currently you are validating it as UUID in the server and the test case generates a UUIDv4\r\n\r\nI am not aware of any UUID handling in our current code base, besides for TANs (which are not stored on the server).

packages are skipped in case the payload (amount of keys) is too small. The threshold should be configurable, and defaulted to 50 for now.\n", "hints_text": "Maybe combine with #140 \n**Alternative suggestion: Pad packages with random dummy keys if too small**\r\n\r\nThinking a bit further into the hoped for future, when new infections are becoming rare, this might lead to unnecessary (possibly quite long) delays in notifications being sent. Could one instead use random dummy keys to pad every package that is too small to maybe 50 or 100 keys (or possibly padding to a randomised amount so an outsider can't even determine whether there any dummies are in the set).\r\n\r\nThis would impact required data volumes marginally - in the worst case, if 75 dummy keys are added every hour, this would represent only 50 kiB per day (or 3% of your bandwidth example in the architecture document) if I did not miscalculate. Since this would only occur in a low load situation anyway, this should be acceptable.\nThrehold is now: 140\nI like the padding idea - @MKusber do you think we can do this from a DPP/security perspective?\nHey @MikeJayDee, after some investigation, @michael-burwig and me decided that we will go for the \"shifting\" approach instead of the \"padding\" approach for this release. For clarification:\r\n\r\n**\"Shifting\" approach:**\r\n- If a package is too small (number of keys submitted in a timeframe is below a configurable threshold), then it will not be distributed (there will be zero keys in that package)\r\n- The keys that would have been distributed in that run are \"shifted\" to the next distribution run\r\n- Rinse and repeat until a package can be assembled that contains enough keys (above the configurable threshold)\r\n\r\n**\"Padding\" approach:**\r\n- If a package is too small, then it will be padded with random / fake keys until the threshold is matched (or exceeded)\r\n\r\nAs you have rightly pointed out, the main disadvantage of the \"shifting\" approach is that it introduces an artificial delay in the distribution of keys. This means that people will not be warned about a potential COVID exposure as quickly as possible, but that the CWA server will wait with the distribution until enough submissions have been made. Especially as the number of submissions decreases, this delay will become significant.\r\n\r\nThis disadvantage, of course, doesn't exist with the \"padding\" approach. However, the purpose of this whole \"threshold\" feature is to preserve peoples anonymity and to not allow anyone to create movement profiles. In order to achieve that, it must be impossible to match a specific temporary exposure key (TEK) to any particular person. In the \"shifting\" approach, this is achieved by ensuring that a single person's TEKs are always mashed together with enough other people's real TEKs to get lost in the shuffle. In the \"padding\" approach, this is achieved by mashing a single person's TEKs together with artificially/randomly generated TEKs. In order to make the \"padding\" approach equally as secure and privacy preserving, we would need to make real TEKs and artificially/randomly generated TEKs absolutely indistinguishable from one another. We decided for the \"shifting\" approach for this release because we are not 100% certain that we can achieve that - for the following reasons:\r\n\r\nThere are 4 fields in a TEK:\r\n- Key data\r\n- Transmission risk level\r\n- Rolling start interval number\r\n- Rolling period\r\n\r\n\"Key data\" is random by nature and can easily be generated - no problem there. \"Rolling period\" is always 144 - no problem here either. However, in the real world, \"transmission risk levels\" and \"rolling start interval numbers\" each follow some statistical distribution. In order to make real and fake TEKs indistinguishable to any reasonably certainty, we would need to make sure, that the fake TEKs follow the same distribution as the real ones. The problem is, that we are not sure what the exact properties of that distribution are (and how they change over time). We can thus not confidently guarantee that one wouldn't be able to distinguish random and real TEKs through statistical analysis.\r\n\r\nSince data privacy and protection are the foundation of this whole project, we decided to not take this risk and go with the safer but less accurate solution.\r\n\r\nNow, it might be entirely possible that there is a solution to this problem that we just don't see. But since time is of the essence right now (and we can not wait for a scientifically substantiated analysis of the \"padding\" approach), we decided to go for the \"shifting\" approach for the initial release.\r\n\r\nAnyways. Thank you very much for sharing your idea, @MikeJayDee. We forwarded your idea and the open questions outlined above to our scientific partners and will keep you posted on any updates \ud83d\udc4d ", "created_at": "2020-06-01T17:31:01Z"}

[here](https://github.com/corona-warn-app/cwa-server/blob/master/common/protocols/src/main/proto/app/coronawarn/server/common/protocols/internal/risk_score_parameters.proto)) is defined as follows:\r\n```proto3\r\nmessage AttenuationRiskParameters {\r\n  RiskLevel gt_73_dbm = 1;            // A > 73 dBm, lowest risk\r\n  RiskLevel gt_63_le_73_dbm = 2;      // 63 < A <= 73 dBm\r\n  RiskLevel gt_51_le_63_dbm = 3;      // 51 < A <= 63 dBm\r\n  RiskLevel gt_33_le_51_dbm = 4;      // 33 < A <= 51 dBm\r\n  RiskLevel gt_27_le_33_dbm = 5;      // 27 < A <= 33 dBm\r\n  RiskLevel gt_15_le_27_dbm = 6;      // 15 < A <= 27 dBm\r\n  RiskLevel gt_10_le_15_dbm = 7;      // 10 < A <= 15 dBm\r\n  RiskLevel lt_10_dbm = 8;            // A <= 10 dBm, highest risk\r\n}\r\n```\r\n\r\nThere is no value range that includes an attenuation of **exactly** 10dBm.\r\n\r\n## Expected behaviour\r\nAccording to the [Google/Apple spec](https://developer.apple.com/documentation/exposurenotification/enexposureconfiguration), the last value range should be \"less than or equal to 10dBm\" (`le_10_dbm`):\r\n\r\n![image](https://user-images.githubusercontent.com/8984460/86034663-57f91580-ba3b-11ea-9444-e5020e6dcc46.png)\r\n\r\n## Possible Fix\r\n- Correct the last attenuation value range according to spec\r\n- Update dependent code/configuration respectively ([here](https://github.com/corona-warn-app/cwa-server/blob/b8afdce9a3bc8fd927fe4ec9be2e910ee8f1635d/services/distribution/src/test/resources/objectstore/publisher/examplefile),

context\r\n- This \"bug\" doesn't have any technical implications and should only be fixed for consistency\r\n- Downwards-compatibility of the proto messages should not be infringed by the proposed change\n", "hints_text": "", "created_at": "2020-07-01T11:58:13Z"}

If you want to trigger additional distribution runs, run ```docker-compose run distribution```.\n@@ -60,10 +60,10 @@ Service           | Description | Endpoint and Default Credentials\n ------------------|-------------|-----------\n submission        | The Corona-Warn-App submission service                                                      | `http://localhost:8000` <br> `http://localhost:8006` (for actuator endpoint)\n distribution      | The Corona-Warn-App distribution service                                                    | NO ENDPOINT\n-postgres          | A [postgres] database installation                                                          | `postgres:8001` <br> Username: postgres <br> Password: postgres\n+postgres          | A [postgres] database installation                                                          | `localhost:8001` <br> `postgres:5432` (from containerized pgadmin) <br> Username: postgres <br> Password: postgres\n pgadmin           | A [pgadmin](https://www.pgadmin.org/) installation for the postgres database                | `http://localhost:8002` <br> Username: user@domain.com <br> Password: password\n cloudserver       | [Zenko CloudServer] is a S3-compliant object store  | `http://localhost:8003/` <br> Access key: accessKey1 <br> Secret key: verySecretKey1\n-verification-fake | A very simple fake implementation for the tan verification.                                 | `http://localhost:8004/version/v1/tan/verify` <br> The only valid tan is \"edc07f08-a1aa-11ea-bb37-0242ac130002\"\n+verification-fake | A very simple fake implementation for the tan verification.                                 | `http://localhost:8004/version/v1/tan/verify` <br> The only valid tan is `edc07f08-a1aa-11ea-bb37-0242ac130002`.\n \n ##### Known Limitation\n \n@@ -97,6 +97,32 @@ To prepare your machine to run the CWA project locally, we recommend that you fi\n * [Postgres]\n * [Zenko CloudServer]\n \n+If you are already running a local Postgres, you need to create a database `cwa` and run the following setup scripts:\n+\n+* Create the different CWA roles first by executing [create-roles.sql](setup/create-roles.sql).\n+* Create local database users for the specific roles by running [create-users.sql](./local-setup/create-users.sql).\n+* It is recommended to also run [enable-test-data-docker-compose.sql](./local-setup/enable-test-data-docker-compose.sql)\n+, which enables the test data generation profile.

This configuration file is\n+divided into different sub-categories:\n+\n+- Some general configuration, which isn't divided into sub-categories\n+- `paths` - Local paths, that are used during the export creation\n+- `tek-export` - Configuration for the exported archive, that is saved on the S3-compatible storage\n+- `api` - API configuration, configures the API, which is used by the mobile app to query diagnosis keys\n+- `signature` - Signature configuration, used for signing the exports\n+- `objectstore` - Configuration for the S3 compatible object storage\n+\n+## Object Store\n+\n+The communication with the S3 compatible object storage, that is hosted by Deutsche Telekom is achieved through AWS SDK\n+v2. The files, that will be uploaded to the S3 compatible storage are created on local storage first (output path\n+defined in application configuration) and are then uploaded to the storage provider.\n+\n+### Headers\n+\n+Up to three headers are set during upload, depending on the configuration properties.\n+\n+#### `Cache-Control`\n+\n+Defines the maximum amount of time a published resource is considered fresh, when held in cache. Will be set for each\n+upload. The default value is 300 seconds.\n+\n+#### `x-amz-acl`\n+\n+Defines the canned ACL for the uploaded file. Is only set if [`set-public-read-acl-on-put-object`] is set to true in the\n+configuration properties. Will be `public-read` in that case, which grants full control to the owners and read-access to\n+AllUsers. This setting should only be used when running with the application with the local Zenko Cloudserver.\n+\n+#### `cwa-hash`\n+\n+Custom header, which adds the MD5 hash of the archive contents (export.bin). If the file isn't an archive, the contents\n+of the file will be used to build the hash (index files). This header is used to determine, whether a file should be\n+uploaded or not. If the hash for the file is the same as the hash available on the S3 compatible storage it will not be\n+uploaded, since the contents of that specific file did not change, so there is no need to re-upload the file. If the\n+hash differs, or the file is not available on the S3 compatible storage the file will be uploaded.\n+\n+This header is needed, since it is not possible to create byte-identical archives when using ECDSA due to its\n+non-deterministic nature.\n+\n+### Threading\n+\n+The upload operations are being run in multiple threads in order to increase performance. The number of threads is\n+defined in the application configuration. Each upload operation is passed to Spring Boot's `ThreadPoolTaskExecutor`,\n+which then distributes them across the available threads. Once all tasks are submitted, the logic checks, whether all\n+threads have terminated before shutting down the thread pool. If errors are thrown, they are handled as explained in the\n+following section.\n+\n+### Error Handling\n+\n+In order to increase resilience of the distribution service two error handling measures were introduced.\n+\n+The first one being Spring Boot's Retry logic, which is applied to all S3 operations with the number of retries being\n+specified in the application configuration. This results in Spring Boot retrying the operation up to three times, with a\n+two second pause in between.\n+\n+The second part will catch operations, that have failed even after retrying them through SpringBoot's Retry logic. If\n+more than five uploads fail (can be configured in the application configuration) the program will terminate with an\n+error, if less than five operations have failed so far the error will just be logged to console, but the upload will\n+continue.\n+\n+The error handling is designed to handle intermediate errors, like short connection problems. If too many operations\n+fail it is safe to assume, that a bigger problem is occurring and that subsequent operations will also fail. In this\n+case the program is terminated to prevent unnecessary load.\n+\n+### Retention\n+\n+The same 14 days retention period (like the database) is also enforced on the S3 compatible storage. Each distribution\n+run will execute the retention policy.\n+\n+When data deletion is executed on the object store, the object store is instructed to delete all files with the following\n+prefix:\n+\n+`version/v1/diagnosis-keys/country/DE/<date>`\n+\n+In which `<date>` stands for the ISO formatted date (e.g. `2012-06-05`), and is before the retention cutoff date\n+(today - 14 days).\n+\n+## Assembly Process\n+\n+The exported diagnosis-keys are being organized in hourly and daily archives. The folder structure is as follows:\n+`/version/<version>/diagnosis-keys/country/<ISO-3166-country>/date/<YYYY-MM-DD>/hour/<hh>/index`. The version, country,\n+date and hour directory also contain an index file each, listing all the subdirectories. All generated files are named\n+`index`, which acts as a workaround to also support files & folders with the same name - e.g.\n+`version/v1/diagnosis-keys/country` is both a file and the folder `version/v1/diagnosis-keys/country/`. S3 supports this\n+concept, but writing this structure to the local disk is not supported. Therefore, this country file will be assembled as\n+`version/v1/diagnosis-keys/country/index`. The `/index` part will then be removed upon S3 upload.\n+\n+For each assembly run the diagnosis keys for the last 14 days are queried. Based on the result, hour and their parent\n+directories are created and the keys are added to their respective archives. To which archive the key should be added is\n+determined by the distribution timestamp.\n+\n+The diagnosis keys need to be expired for at least two hours, before they can be distributed. This means that if the key\n+has been submitted within two hours after the expiry date, it cannot be published immediately. Therefore a distribution\n+timestamp is calculated, which is either the submission timestamp, or, if the submission timestamp is within two hours\n+after the expiry date, the expiry date plus two hours. This ensures compliance with the specification from Google and\n+Apple.\n+\n+Each run creates all hourly and daily archives for the last 14 days. To prevent unnecessary uploads the\n+[`cwa-hash`](#cwa-hash) header has been introduced.\ndiff --git a/docs/INFRASTRUCTURE.md b/docs/INFRASTRUCTURE.md\nnew file mode 100644\n--- /dev/null\n+++ b/docs/INFRASTRUCTURE.md\n@@ -0,0 +1 @@\n+# CWA-Server Infrastructure\ndiff --git a/docs/PERSISTENCE.md b/docs/PERSISTENCE.md\nnew file mode 100644\n--- /dev/null\n+++ b/docs/PERSISTENCE.md\n@@ -0,0 +1 @@\n+# CWA-Server Persistence\ndiff --git a/docs/QUALITY_ASSURANCE.md b/docs/QUALITY_ASSURANCE.md\nnew file mode 100644\n--- /dev/null\n+++ b/docs/QUALITY_ASSURANCE.md\n@@ -0,0 +1 @@\n+# CWA-Server Quality Assurance\ndiff --git a/docs/README.md b/docs/README.md\nnew file mode 100644\n--- /dev/null\n+++ b/docs/README.md\n@@ -0,0 +1,11 @@\n+# CWA-Server Documentation\n+\n+| Documentation | Description |\n+| --- | --- |\n+| [Architecture](./ARCHITECTURE.md) | Architectural overview |\n+| [Submission Service](./SUBMISSION.md) | Documentation of the submission service |\n+| [Distribution Service](./DISTRIBUTION.md)   | Documentation of the distribution service |\n+| [Persistence](./PERSISTENCE.md) | Documentation of the persistence module |\n+| [Infrastructure](./INFRASTRUCTURE.md) |  Documentation of infrastructure related topics |\n+| [Quality Assurance](./QUALITY_ASSURANCE.md) | Documentation of testing and quality assurance |\n+| [Security](./SECURITY.md) | Documentation of security related topics |\ndiff --git a/docs/SECURITY.md b/docs/SECURITY.md\nnew file mode 100644\n--- /dev/null\n+++ b/docs/SECURITY.md\n@@ -0,0 +1,21 @@\n+# CWA-Server Security\n+\n+## TLS Configuration\n+\n+The cwa-server uses encrypted connections for external and internal communication.

scenario\n## Describe the bug\r\n\r\nReducing the number of submission service service pods leads to immediate termination of request processing on the service instance that is shutting down while. This results in clients observing a failing requests.\r\nIn the worst case scenario, submission processing is interrupted after a TAN was verified successfully but the corresponding diagnosis keys have not been persisted yet.\r\n\r\n## Expected behaviour\r\n\r\nOn a service instance that is shutting down, no new requests shall be accepted. Requests that are already being processed at the time shall be given a grace period in which they are allowed to finish processing.\r\n\r\n## Possible Fix\r\n\r\n- ``ThreadPoolExecutor.awaitTermination`` and similar concepts\r\n\r\n## Additional context\r\nFrom a previous performance testing run:\r\n<!-- Add any other context about the problem here. -->\r\n![image](https://user-images.githubusercontent.com/64439292/84418312-4c25ea80-ac17-11ea-9b2e-ca398f877508.png)\r\n\r\n\nLog4j improper shutdown\n## Current Behaviour\r\n\r\nOn Distribution service shutdown, the following log entry appears, indicating Log4j did not shutdown properly. Also, it is logged using the fallback `SimpleLogger` which uses a different timestamp date format and is not consistent with other log entries and therefore may not be picked up by monitoring tools.\r\n \r\n`2020-06-12 09:05:23,582 SpringContextShutdownHook WARN Unable to register Log4j shutdown hook because JVM is shutting down.

As they are currently not being used by the mobile app, there would be no impact.</del>\r\n2. <del>Run retention only once per day and not on every job. Can be problematic in case this one job did not trigger or failed, so the next retention run would only occur after 24 hours. Not a big issue though.</del>\r\n3. Store some pointer/information on the database which indicates which keys were already distributed. There are some edge cases which make this approach more complicated though (e.g. shifting keys due to 2 hours key validity expiration).\r\n\r\nEdit: Daily files are just as affected as hourly files.

Denial-of-Service in Download Service\nRating: Informational\r\n\r\nDescription:\r\nThe download service component of the cwa-server backend can be forced into an endless loop by a malicious or faulty federation gateway server. When downloading new batches from the federation gateway server, the download service checks the nextBatchTag header of the federation gateway server\u2019s response. If this header is set, the download service will continue requesting a batch with this tag. It will not stop as long as the server includes this header. This can trap the download service in an endless loop.\r\nThis highly depends on the behavior and implementation of the federation gateway server. However, even a non-malicious, faulty implementation might trigger this issue. Additionally, the issue was sometimes hard to reproduce as the server first has to be forced to request new batches (which in some cases required setting the EFGS_ENABLE_DATE_BASED_DOWNLOAD configuration to true).\r\n\r\nAffected System:\r\ncwa-server (commit 4f3f460f580ea5d548dff0e3ceb739908c83d1a7)\r\n\r\nProof of Concept:\r\nThe following screenshots show the offending lines in the FederationBatchProcessor.java:\r\n\r\n<img width=\"846\" alt=\"Download Service DoS Offending Code\" src=\"https://user-images.githubusercontent.com/65443025/98435998-dcd5f900-20d7-11eb-9f5e-3fb7f449ca58.png\">\r\n\r\nThe following snippets show a minimalistic federation gateway server mock that returns invalid data but sets the nextBatchTag header on each response. The first request needs to fail (in this case implemented by sending an invalid HTTP request body) so that the batch tag is added to the list of unprocessed batches.\r\n<img width=\"775\" alt=\"snippet-1\" src=\"https://user-images.githubusercontent.com/65443025/98436046-5c63c800-20d8-11eb-843e-47e98b9c2ed7.png\">\r\n<img width=\"779\" alt=\"snippet-2\" src=\"https://user-images.githubusercontent.com/65443025/98436048-61c11280-20d8-11eb-9d77-43ebd770a556.png\">\r\n\r\n\r\nThe following screenshot shows the failing first request on the first run of the download service:\r\n<img width=\"824\" alt=\"Download Service DoS First Invalid Request\" src=\"https://user-images.githubusercontent.com/65443025/98436059-87e6b280-20d8-11eb-9ad0-7ceaaa557add.png\">\r\n\r\n\r\nThe next screenshot shows the log output of the download service when it is run again. It can be seen that the server will endlessly try to request a next batch.\r\n<img width=\"845\" alt=\"Download Service DoS Endless Loop Log\" src=\"https://user-images.githubusercontent.com/65443025/98436074-ab116200-20d8-11eb-8c3c-ac545d9c1b07.png\">\r\n\r\n\r\n\r\nRecommended Controls: \r\nThe while loop should be adapted so that it is not possible for it to continue forever. The received nextBatchTag header should be checked. If it is already contained in the list of unprocessed batches, it should not be added again. This does not protect against a malicious server that sends different batch tags on each request. Therefore, alternatively, a timeout value or a maximum number of retries could be introduced.\r\n\n", "hints_text": "", "created_at": "2020-11-09T15:39:20Z"}

In Android Studio check out CWA Android app release/1.4.x\r\n2. Run CWA on Pixel 3a API 33 Android device emulator in Debug mode\r\n3. Open Logcat in Android Studio and enter search term \"UpdateChecker\"\r\n\r\nThe log shows the following:\r\n\r\n```\r\nUpdateChecker           de.rki.coronawarnapp.dev             E  minVersionStringFromServer:1.0.4\r\nUpdateChecker           de.rki.coronawarnapp.dev             E  Current app version:1.4.0\r\nUpdateChecker           de.rki.coronawarnapp.dev             E  needs update:false\r\n```\r\n\r\nAlternatively install old released versions from https://www.apkmirror.com/apk/robert-koch-institut/corona-warn-app/.

This is consistent with min-Android being set to `1.0.4` in production.\r\n\r\n\r\n## Technical details\r\n\r\n- Android Studio Dolphin | 2021.3.1 Patch 1\r\n- Pixel 3a API 33 Android device emulator\r\n- CWA Android 1.4.0 (note that this version was not released. Version 1.5 followed version 1.3)\r\n\r\n## Possible Fix\r\n\r\nClarify what the minimum enforced version of CWA Android in production is supposed to be and ensure alignment of https://github.com/corona-warn-app/cwa-server/blob/main/services/distribution/src/main/resources/application.yaml with the values used in production.\r\n\n", "hints_text": "- FYI: I opened https://github.com/corona-warn-app/cwa-server/issues/1963 asking the team to check for other differences between this repositories `main` branch & the production environment. \nAlso I would expect `min-android-version-code` /  `minVersionCode=48` and not `31` to be served.", "created_at": "2022-11-21T14:08:50Z"}
