Restart Required: No
Instructions:
No official patch available. Vendor has not responded to disclosure. Consider alternative software or implement workarounds.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block file uploads to the vulnerable endpoint or restrict file types.
File Upload Validation
allImplement server-side file type validation, size limits, and content inspection for uploads.
🧯 If You Can't Patch
- Isolate the affected system from critical networks and implement strict network segmentation.
- Implement application-level input validation and file upload restrictions at the web server or reverse proxy level.
🔍 How to Verify
Check if Vulnerable:
Attempt to upload a test file (e.g., .txt, .php) to /agent/profile/edit endpoint and check if it's accepted without proper validation.Check Version:
Check software version in admin panel or configuration files. Exact command depends on deployment.Verify Fix Applied:
Test file upload functionality with various file types to ensure proper validation and rejection of malicious files.📡 Detection & Monitoring
Log Indicators:
