📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including sensitive passenger data theft, administrative credential extraction, and potential system takeover via SQL injection leading to remote code execution.
Likely Case
Unauthorized access to passenger records, personal information theft, and potential manipulation of booking/pass data.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permission restrictions in place.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. If no patch available, implement workarounds immediately. 3. Consider migrating to a supported/patched version if available.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the searchdata parameter
Modify /download-pass.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM passes WHERE pass_number = ?'); $stmt->bind_param('s', $searchdata);
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns in the searchdata parameter
Add WAF rule: deny requests where searchdata contains SQL keywords like UNION, SELECT, INSERT, DELETE, DROP, OR 1=1
🧯 If You Can't Patch
- Isolate the vulnerable system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all database queries from the affected system
🔍 How to Verify
Check if Vulnerable:
Test the /download-pass.php endpoint with SQL injection payloads in the searchdata parameter (e.g., searchdata=' OR '1'='1)Check Version:
Check system documentation or admin panel for version information; typically found in readme files or configuration filesVerify Fix Applied:
Test with the same SQL injection payloads after implementing fixes; successful fix should return normal results or error messages without database interaction📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from web server IP
- Multiple failed login attempts following SQL error patterns
- Long or unusual search parameters in access logs
Network Indicators:
- HTTP requests to /download-pass.php with SQL keywords in parameters
- Unusual database traffic patterns from web application server
SIEM Query:
source="web_access.log" AND uri="/download-pass.php" AND (searchdata="*UNION*" OR searchdata="*SELECT*" OR searchdata="*OR 1=1*")
