🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Implement workarounds or migrate to a different travel agency system.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify daily_expenditure_edit.php to validate the id parameter and use prepared statements
Replace vulnerable SQL queries with parameterized queries using PDO or mysqli prepared statements
Web Application Firewall (WAF)
allDeploy a WAF to block SQL injection attempts
Configure WAF rules to block SQL injection patterns in URL parameters
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement network segmentation to limit database server access
🔍 How to Verify
Check if Vulnerable:
Test the daily_expenditure_edit.php endpoint with SQL injection payloads in the id parameterCheck Version:
Check the software version in the system configuration or about pageVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and that parameterized queries are implemented📡 Detection & Monitoring
