🛠️ 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 upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for email/contactno parameters in forgot-password.php.
Edit PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE email = ?'); $stmt->bind_param('s', $email);
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting the forgot-password endpoint.
Configure WAF to detect and block patterns like ' OR '1'='1, UNION SELECT, etc., in POST parameters.
🧯 If You Can't Patch
- Disable or restrict access to /forgot-password.php endpoint via firewall rules or web server configuration.
- Implement network segmentation to isolate the ticketing system from critical databases and limit potential lateral movement.
🔍 How to Verify
Check if Vulnerable:
Test the /forgot-password.php endpoint with SQL injection payloads (e.g., ' OR '1'='1) in email/contactno parameters and observe database errors or unexpected behavior.Check Version:
Check system documentation or admin panel for version information; typically displayed in footer or about page.Verify Fix Applied:
After applying workarounds, retest with SQL injection payloads to ensure no database errors or unauthorized access occurs.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs (e.g., MySQL syntax errors), multiple failed login attempts from single IPs, unexpected database queries.
Network Indicators:
- HTTP POST requests to /forgot-password.php with suspicious parameters containing SQL keywords like UNION, SELECT, OR, --.
SIEM Query:
source="web_server_logs" AND uri="/forgot-password.php" AND (param="email" OR param="contactno") AND (value="*OR*" OR value="*UNION*" OR value="*SELECT*")
