CVE-2025-12382
📋 TL;DR
This path traversal vulnerability in Algosec Firewall Analyzer allows authenticated users to upload files to restricted directories, potentially leading to code injection. It affects Linux 64-bit installations of specific versions. Attackers could execute arbitrary code on affected systems.
💻 Affected Systems
- Algosec Firewall Analyzer
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise via remote code execution, allowing attackers to install malware, exfiltrate sensitive firewall configuration data, or pivot to other network systems.
Likely Case
Unauthorized file upload leading to web shell deployment, data theft, or service disruption of the firewall analyzer.
If Mitigated
Limited impact if proper file upload validation and directory restrictions are enforced, though authentication bypass remains possible.
🎯 Exploit Status
Exploitation requires authenticated access but path traversal vulnerabilities are typically straightforward to exploit once discovered.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: A33.0 build 321+, A33.10 build 211+
Vendor Advisory: https://techdocs.algosec.com/en/cves/Content/tech-notes/cves/cve-2025-12382.htm
Restart Required: Yes
Instructions:
1. Download latest version from Algosec support portal. 2. Backup current configuration. 3. Stop Algosec Firewall Analyzer service. 4. Install updated version. 5. Restart service and verify functionality.
🔧 Temporary Workarounds
Restrict File Upload Permissions
linuxTighten file system permissions on upload directories to prevent traversal
chmod 750 /opt/algosec/uploads
chown root:algosec /opt/algosec/uploads
Implement Web Application Firewall Rules

🧯 If You Can't Patch
- Implement strict network segmentation to isolate Algosec Firewall Analyzer from critical systems
- Enforce least privilege access controls and monitor authenticated user activity closely
🔍 How to Verify
Check if Vulnerable:
Check Algosec Firewall Analyzer version via web interface or command: grep 'Version' /opt/algosec/version.txtCheck Version:
cat /opt/algosec/version.txtVerify Fix Applied:
Verify version is A33.0 build 321+ or A33.10 build 211+ and test file upload functionality with traversal attempts📡 Detection & Monitoring
Log Indicators:
- Unusual file upload patterns
- Path traversal strings in web logs (../, ..\, %2e%2e%2f)
- Authentication logs showing unexpected user file upload activity
Network Indicators:
- HTTP POST requests containing path traversal sequences to upload endpoints
SIEM Query:
