allPrevent exploitation by disabling the vulnerable thumbnail rendering component
Edit configuration to set 'video_thumbnails' to false or remove video processing capabilities
Restrict video file uploads
allBlock or quarantine video file uploads to prevent malicious files from reaching the vulnerable component
Configure web server or application firewall to block .mp4, .avi, .mov, .mkv uploads
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all file upload parameters
- Deploy WAF rules to detect and block command injection patterns in file upload requests
🔍 How to Verify
Check if Vulnerable:
Check your files.gallery version. If it's between 0.3.0 and 0.11.0 inclusive, you are vulnerable.Check Version:
Check the files.gallery configuration file or package manager for version informationVerify Fix Applied:
Verify installation of version 0.11.1 or later and test that video thumbnail generation works without security issues.📡 Detection & Monitoring
