📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or full system takeover via privilege escalation.
Likely Case
Unauthorized access to sensitive student records, grades, personal information, and potential modification of academic data.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation in place.
🎯 Exploit Status
Exploit requires access to admin functionality; SQL injection via ID parameter manipulation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Consider implementing parameterized queries in the affected PHP file or migrating to a supported alternative.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the ID parameter in /admin_single_student_update.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('UPDATE students SET ... WHERE id = ?'); $stmt->bind_param('i', $id);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint
Configure WAF to block requests containing SQL keywords like UNION, SELECT, INSERT, DELETE when targeting /admin_single_student_update.php
🧯 If You Can't Patch
- Restrict network access to the University Management System to trusted IP addresses only
- Implement strong authentication and monitor admin_single_student_update.php access logs for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Test the /admin_single_student_update.php endpoint with SQL injection payloads in the ID parameterCheck Version:
Check software documentation or about page for version informationVerify Fix Applied:
Verify that parameterized queries are implemented and SQL injection attempts are properly rejected📡 Detection & Monitoring
