🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch available. Monitor vendor website for updates. Consider implementing input validation and parameterized queries as temporary mitigation.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation and sanitization of the ID parameter in /ajax.php
Modify ajax.php to validate ID parameter using is_numeric() or similar functions
Implement prepared statements with parameterized queries
Web Application Firewall Rules
allBlock SQL injection patterns targeting the vulnerable endpoint
WAF rule: Block requests to /ajax.php?action=delete_position with suspicious SQL patterns in ID parameter
🧯 If You Can't Patch
- Isolate the payroll system in a separate network segment with strict access controls
- Implement database-level protections: restrict application database user permissions, enable SQL injection detection logging
🔍 How to Verify
Check if Vulnerable:
Test the /ajax.php?action=delete_position endpoint with SQL injection payloads in the ID parameter (e.g., ID=1' OR '1'='1)Check Version:
Check system version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and that input validation is properly implemented📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts following SQL injection patterns
- Access to /ajax.php?action=delete_position with suspicious parameters
Network Indicators:
- HTTP requests to /ajax.php?action=delete_position containing SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
