CVE-2021-44312
📋 TL;DR
This CSRF vulnerability in Firmware Analysis and Comparison Tool v3.2 allows attackers to perform unauthorized actions as logged-in administrators by tricking them into visiting a malicious webpage. Only administrators using the web interface are affected, but successful exploitation could lead to complete system compromise.

⚠️ Risk & Real-World Impact
Worst Case
Attacker gains full administrative control over the tool, potentially modifying firmware analysis results, accessing sensitive data, or executing arbitrary code on the server.
Likely Case
Attacker modifies system settings, creates new administrative accounts, or exfiltrates sensitive firmware analysis data.
If Mitigated
With proper CSRF protections and administrator awareness, exploitation risk is minimal as it requires administrator interaction with malicious content.
🎯 Exploit Status
Exploitation requires social engineering to trick administrator into visiting malicious page while logged in.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
No official patch available. Implement CSRF tokens and referer validation in the application code.
🔧 Temporary Workarounds
Implement CSRF Protection
allAdd CSRF tokens to all state-changing requests and validate them server-side
Application code modification required - no single command
Use SameSite Cookies
allSet SameSite=Strict or Lax on session cookies to prevent cross-site requests
Set-Cookie: session=value; SameSite=Strict; Secure; HttpOnly
🧯 If You Can't Patch
- Restrict administrator access to trusted networks only
- Implement web application firewall with CSRF protection rules
- Educate administrators about phishing risks and safe browsing practices
- Use separate browser profiles for administrative tasks
🔍 How to Verify
Check if Vulnerable:
Check if application lacks CSRF tokens on forms and state-changing endpoints. Test by creating a malicious page that submits requests to the tool.Check Version:
Check application version in web interface or configuration filesVerify Fix Applied:
Verify that all POST/PUT/DELETE requests require valid CSRF tokens and that SameSite cookie attributes are properly set.📡 Detection & Monitoring
Log Indicators:
- Unusual administrative actions from unexpected IPs
- Multiple failed CSRF token validations
- Administrative actions without corresponding user interface access logs
Network Indicators:
- Cross-origin requests to administrative endpoints
- Requests missing expected CSRF tokens
SIEM Query:
source="web_logs" AND (action="admin_*" OR endpoint="/admin/*") AND NOT (referer CONTAINS "trusted-domain.com" OR csrf_token EXISTS)
