🔧 Temporary Workarounds
Web Application Firewall Rule
allBlock or restrict access to /file/upload endpoint
# WAF specific - block POST requests to /file/upload
Input Validation Filter
allImplement server-side file type validation before processing uploads
# Java filter to validate file extensions and MIME types
🧯 If You Can't Patch
- Disable or restrict access to the /file/upload endpoint completely
- Implement strict file upload validation including file type checking, size limits, and content verification
🔍 How to Verify
Check if Vulnerable:
Test if you can upload arbitrary files (e.g., .jsp, .php, .exe) to /file/upload endpoint without validationCheck Version:
git log --oneline -1 # Check latest commit hash against vulnerable rangeVerify Fix Applied:
Attempt to upload restricted file types and verify they are rejected with proper error messages📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to /file/upload
- Uploads of executable file types
- Large number of upload requests
Network Indicators:
- POST requests to /file/upload with suspicious file extensions
- Unusual outbound traffic after uploads
SIEM Query:
source="application.logs" AND (uri="/file/upload" AND (file_extension="jsp" OR file_extension="php" OR file_extension="exe"))
