Patch Version: Unknown
Vendor Advisory: http://roothub.com
Restart Required: No
Instructions:
Check vendor website for updates. If unavailable, implement workarounds immediately.
🔧 Temporary Workarounds
Restrict File Upload Types
allConfigure web server to reject JSP file uploads and limit to safe extensions.
# Configure in web server (e.g., Apache/Nginx) to block .jsp uploads
Implement File Upload Validation
allAdd server-side validation to check file types and content before saving.
# Add validation in upload() function to verify file type and path
🧯 If You Can't Patch
- Isolate affected systems from internet and critical internal networks.
- Implement strict network segmentation and monitor for unusual file upload activity.
🔍 How to Verify
Check if Vulnerable:
Check if running Roothub v2.5 and if upload() function with customPath parameter is accessible.Check Version:
# Check application version in configuration or admin panelVerify Fix Applied:
Test file upload with JSP extension; it should be rejected or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to custom paths
- JSP file creation in web directories
Network Indicators:
- HTTP POST requests to upload endpoints with JSP files
SIEM Query:
