CWE-1385: Missing Origin Validation in WebSockets
Weakness ID : 1385
Structure : Simple
Abstraction : Variant
Description
The product uses a WebSocket, but it does not properly verify that the source of data or
communication is valid.
Extended Description
WebSockets provide a bi-directional low latency communication (near real-time) between a client
and a server. WebSockets are different than HTTP in that the connections are long-lived, as the
channel will remain open until the client or the server is ready to send the message, whereas in
HTTP, once the response occurs (which typically happens immediately), the transaction completes.
A WebSocket can leverage the existing HTTP protocol over ports 80 and 443, but it is not limited
to HTTP. WebSockets can make cross-origin requests that are not restricted by browser-based
protection mechanisms such as the Same Origin Policy (SOP) or Cross-Origin Resource Sharing
(CORS). Without explicit origin validation, this makes CSRF attacks more powerful.

The consequences will vary depending on the nature of
the functionality that is vulnerable to CSRF. An attacker
could effectively perform any operations as the victim.
If the victim is an administrator or privileged user, the
consequences may include obtaining complete control
over the web application - deleting or stealing data,
uninstalling the product, or using it to launch other attacks
against all of the product's users. Because the attacker has
