🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/student-record-system-php
Restart Required: No
Instructions:
1. Check vendor website for updated version. 2. If no patch, implement parameterized queries in change-password.php. 3. Validate and sanitize currentpassword input.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to reject malicious SQL characters in currentpassword parameter.
Add PHP validation: if(preg_match('/[\'\"\;\-\-\/\*\=\s]/', $_POST['currentpassword'])) { die('Invalid input'); }
Web Application Firewall Rule
allBlock SQL injection patterns targeting change-password.php endpoint.
WAF rule: Block requests to /change-password.php containing SQL keywords in POST parameters.
🧯 If You Can't Patch
- Implement network segmentation to restrict access to the application.
- Enable detailed logging of all change-password.php requests and monitor for SQL patterns.
🔍 How to Verify
Check if Vulnerable:
Test change-password.php with SQL injection payloads in currentpassword parameter (e.g., ' OR '1'='1).Check Version:
Check application files or admin panel for version 3.20 indication.Verify Fix Applied:
Verify parameterized queries are implemented and test with same SQL injection payloads expecting failure.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed password change attempts with special characters
Network Indicators:
- HTTP POST requests to change-password.php containing SQL keywords like UNION, SELECT, OR
SIEM Query:
source="web_logs" AND uri="/change-password.php" AND (request_body LIKE "%OR%" OR request_body LIKE "%UNION%" OR request_body LIKE "%SELECT%")
