🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates or consider alternative solutions.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting the /ajax.php endpoint with save_deductions action.
Input Validation Filter
allAdd server-side input validation to sanitize the ID parameter before processing.
🧯 If You Can't Patch
- Isolate the payroll system in a separate network segment with strict access controls.
- Implement database-level protections: use parameterized queries, restrict database user permissions, and enable SQL injection logging.
🔍 How to Verify
Check if Vulnerable:
Test the /ajax.php?action=save_deductions endpoint with SQL injection payloads in the ID parameter and observe database errors or unexpected behavior.Check Version:
Check application version in admin panel or configuration files; typically found in about.php or similar pages.Verify Fix Applied:
Verify that SQL injection payloads no longer execute and that proper input validation is implemented.📡 Detection & Monitoring
Log Indicators:
