🔧 Temporary Workarounds
Block access to vulnerable endpoint
allTemporarily block or restrict access to /assets/createNotice.php
# For Apache: RewriteRule ^/assets/createNotice\.php$ - [F,L]
# For Nginx: location ~ ^/assets/createNotice\.php$ { deny all; }
Implement file upload restrictions
allAdd server-side validation for file uploads including file type checking and size limits
🧯 If You Can't Patch
- Implement strict WAF rules to block file upload attempts to the vulnerable endpoint
- Isolate the affected system from critical network segments and monitor for suspicious upload activity
🔍 How to Verify
Check if Vulnerable:
Check if /assets/createNotice.php exists and accepts file uploads without proper validation. Test by attempting to upload a file with a malicious extension.
Check Version:
Check git commit hash: git log --oneline -1
Verify Fix Applied:
Verify that file uploads to /assets/createNotice.php are properly validated and restricted. Test with various file types including executable extensions.
📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to /assets/createNotice.php
- Uploads of files with executable extensions (.php, .exe, .sh)
- Multiple failed upload attempts
Network Indicators:
- POST requests to /assets/createNotice.php with file uploads
- Unusual outbound connections from the server after file uploads
SIEM Query:
source="web_logs" AND uri="/assets/createNotice.php" AND method="POST" AND (file_extension="php" OR file_extension="exe" OR file_extension="sh")
