- Disable or remove the /admin/between-dates-report.php file if functionality is not required
🔍 How to Verify
Check if Vulnerable:
Test the /admin/between-dates-report.php endpoint with SQL injection payloads in the 'fromdate' parameter (e.g., ' OR '1'='1) and observe if database errors or unexpected results occur
Check Version:
Check software version in admin panel or readme files. No specific command available.
Verify Fix Applied:
After implementing workarounds, retest with SQL injection payloads to confirm they are blocked or sanitized
