⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, authentication bypass, remote code execution, and full system takeover.
Likely Case
Unauthorized access to sensitive passenger data (PII, travel records), database manipulation, and potential privilege escalation.
If Mitigated
Limited impact with proper input validation, parameterized queries, and WAF protection in place.
🎯 Exploit Status
Public exploit details available in GitHub repository with simple HTTP request payloads.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
1. Replace vulnerable code with parameterized queries
2. Implement input validation for all user inputs
3. Update to a secure version if available from vendor
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allBlock SQL injection patterns targeting the vulnerable endpoint
WAF specific - configure rules to block patterns like UNION SELECT, OR 1=1, --, ;, etc.
Access Restriction
linuxRestrict access to /ctpms/classes/Master.php endpoint
# Apache: RewriteRule ^ctpms/classes/Master\.php$ - [F]
# Nginx: location ~ ^/ctpms/classes/Master\.php$ { return 403; }
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all traffic to the vulnerable endpoint
🔍 How to Verify
Check if Vulnerable:
Send a test payload to /ctpms/classes/Master.php?f=update_application_status with SQL injection patterns and check for database errors or unexpected responses.Check Version:
Check application version in admin panel or readme files - vulnerable if version is exactly 1.0Verify Fix Applied:
Test the same endpoint with SQL injection payloads after remediation - should return proper error messages or reject malicious input.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /ctpms/classes/Master.php with SQL keywords in parameters
- Database error logs showing SQL syntax errors from web requests
Network Indicators:
- Unusual SQL patterns in HTTP POST/GET parameters
- Multiple rapid requests to the vulnerable endpoint
SIEM Query:
source="web_logs" AND uri="/ctpms/classes/Master.php" AND (query="*UNION*" OR query="*SELECT*" OR query="*OR 1=1*")
