🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Implement workarounds or migrate to alternative software.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify /unit/addunit.php to validate and sanitize the ID parameter using prepared statements.
Replace vulnerable SQL queries with parameterized queries using PDO or mysqli prepared statements.
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the /unit/addunit.php endpoint.
Configure WAF to block SQL injection patterns: ' OR ', ' UNION ', ' SELECT ', ' INSERT ', ' UPDATE ', ' DELETE '
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules to only trusted IP addresses.
- Implement database user with minimal permissions (read-only if possible) for the application.
🔍 How to Verify
Check if Vulnerable:
Test /unit/addunit.php with SQL injection payloads like: ?ID=1' OR '1'='1Check Version:
Check application version in admin panel or readme files.Verify Fix Applied:
Test with same payloads after implementing parameterized queries - should return error or no data.📡 Detection & Monitoring
Log Indicators:
- Multiple requests to /unit/addunit.php with SQL keywords in parameters
- Database error logs showing SQL syntax errors
Network Indicators:
- HTTP requests containing SQL injection patterns to /unit/addunit.php
SIEM Query:
