✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor has not responded to disclosure. Consider workarounds or alternative software.
🔧 Temporary Workarounds
Web Application Firewall Rule
allBlock or sanitize requests containing path traversal patterns in the pathfile parameter
WAF-specific configuration required
Input Validation Filter
allAdd server-side validation to reject pathfile parameters containing '../' or absolute paths
Application-specific code modification required
🧯 If You Can't Patch
- Restrict network access to the CRM application to trusted IPs only
- Implement strict file system permissions to limit what files the web server can read
🔍 How to Verify
Check if Vulnerable:
Test by accessing the vulnerable endpoint with a path traversal payload in the pathfile parameter and checking for file disclosureCheck Version:
Check CRM version in application interface or configuration filesVerify Fix Applied:
Verify that path traversal attempts return error messages or are blocked rather than disclosing files📡 Detection & Monitoring
Log Indicators:

- Unusual file access patterns from web server process
Network Indicators:
- HTTP requests with path traversal sequences in URL parameters
