CVE-2025-54659
📋 TL;DR
This path traversal vulnerability in Fortinet FortiSOAR Agent Communication Bridge allows unauthenticated attackers to read files accessible to the fortisoar user on systems where the agent is deployed. Attackers can exploit this by sending crafted requests to the agent port, potentially exposing sensitive system files. Organizations using FortiSOAR Agent Communication Bridge versions 1.0 or 1.1.0 are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the fortisoar user's accessible files, including sensitive configuration files, credentials, or other critical system data that could lead to further system compromise.
Likely Case
Unauthorized reading of configuration files, logs, or other sensitive data accessible to the fortisoar service account, potentially exposing credentials or system information.
If Mitigated
Limited exposure of non-critical files if proper file permissions and network segmentation are implemented.
🎯 Exploit Status
Exploitation requires network access to the agent port and knowledge of file paths, but no authentication is needed.
🛠️ Fix & Mitigation

🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to FortiSOAR Agent Communication Bridge ports to only trusted sources.
# Use firewall rules to restrict access
# Example: iptables -A INPUT -p tcp --dport <agent_port> -s <trusted_ip> -j ACCEPT
# iptables -A INPUT -p tcp --dport <agent_port> -j DROP
File Permission Hardening
linuxRestrict file permissions for files accessible to the fortisoar user to minimize potential data exposure.
# Review and tighten permissions on sensitive files
# chmod 600 /path/to/sensitive/file
# chown root:root /path/to/sensitive/file
🧯 If You Can't Patch
- Implement strict network segmentation to isolate FortiSOAR Agent Communication Bridge from untrusted networks.
- Monitor for unusual file access patterns and implement file integrity monitoring on critical files.
🔍 How to Verify
Check if Vulnerable:
Check if running FortiSOAR Agent Communication Bridge version 1.0 or 1.1.0 and if the agent port is accessible from untrusted networks.Check Version:
# Check FortiSOAR version via management interface or configuration filesVerify Fix Applied:
Verify the version has been updated to a patched release and test that path traversal attempts are blocked.📡 Detection & Monitoring
