Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes.
🔧 Temporary Workarounds
Input Validation and Sanitization
PHPAdd parameter validation and SQL injection filtering to /staff/index.php
Modify PHP code to use prepared statements with parameterized queries for the 'e' parameter
Web Application Firewall
allDeploy WAF rules to block SQL injection patterns
Add WAF rule: deny requests with SQL keywords in 'e' parameter
🧯 If You Can't Patch
- Isolate the vulnerable system behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from the vulnerable application
🔍 How to Verify
Check if Vulnerable:
Test /staff/index.php with SQL injection payloads in 'e' parameter (e.g., e=1' OR '1'='1)Check Version:
Check software version in admin panel or readme filesVerify Fix Applied:
Verify that SQL injection payloads no longer work and return proper error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts via /staff/index.php
- Database queries with unusual patterns from web server
Network Indicators:
- HTTP requests to /staff/index.php with SQL keywords in parameters
- Unusual database traffic patterns from web server
SIEM Query:
source="web_logs" AND uri="/staff/index.php" AND (param="e" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "OR '1'='1")
