Endpoint Restriction
allRestrict access to /ajax.php?action=delete_payroll endpoint using network controls or application firewalls
# Apache: RewriteRule ^ajax\.php\?action=delete_payroll - [F]
# Nginx: location ~* /ajax\.php\?action=delete_payroll { deny all; }
# IIS: Add request filtering rule
🧯 If You Can't Patch
- Isolate the payroll system on a separate network segment with strict access controls
- Implement database monitoring and alerting for unusual SQL queries or data access patterns
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads: /ajax.php?action=delete_payroll&ID=1' OR '1'='1Check Version:
Check application files or documentation for version information. Typically in readme files, about pages, or configuration files.Verify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages or are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests to /ajax.php?action=delete_payroll with SQL-like parameters
- Database query logs showing unexpected UNION or SELECT statements
Network Indicators:
- HTTP requests containing SQL keywords (UNION, SELECT, OR, --) targeting the vulnerable endpoint
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/ajax.php" AND query="*action=delete_payroll*" AND (query="*OR*" OR query="*UNION*" OR query="*SELECT*" OR query="*--*" OR query="*#*")
