📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, privilege escalation, and full system takeover via SQL injection to RCE chaining.
Likely Case
Unauthorized data access, modification, or deletion of e-pass records and user information.
If Mitigated
Limited impact with proper input validation and WAF protection blocking malicious SQL payloads.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub, making weaponization likely. SQL injection via GET parameter is straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates. Consider migrating to alternative software if no fix is provided.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the viewid parameter
Modify /admin/view-pass-detail.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM passes WHERE id = ?'); $stmt->bind_param('i', $_GET['viewid']);
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: Block requests to /admin/view-pass-detail.php containing SQL keywords in viewid parameter
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls and network segmentation
- Implement application-level input validation and output encoding for all user inputs
🔍 How to Verify
Check if Vulnerable:
Test the /admin/view-pass-detail.php endpoint with SQL injection payloads like: /admin/view-pass-detail.php?viewid=1' OR '1'='1Check Version:
Check application version in admin panel or readme files. System is version 1.0.Verify Fix Applied:
Verify that SQL injection payloads no longer execute and return proper error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests to /admin/view-pass-detail.php with SQL keywords in parameters
Network Indicators:
- HTTP requests containing SQL injection patterns in GET parameters
- Unusual database query patterns from web server
SIEM Query:
