🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes with parameterized queries.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize fname parameter before processing
Implement PHP filter_var() or custom regex validation for fname parameter
WAF Rule
allDeploy web application firewall rules to block SQL injection patterns
Configure WAF to detect and block SQL injection attempts on /signup.php
🧯 If You Can't Patch
- Disable or restrict access to /signup.php endpoint if user registration is not required
- Implement network segmentation to isolate the vulnerable system from sensitive data
🔍 How to Verify
Check if Vulnerable:
Test /signup.php endpoint with SQL injection payloads in fname parameter and observe database errors or unexpected behaviorCheck Version:
Check application version in admin panel or source code commentsVerify Fix Applied:
Attempt SQL injection after fixes and verify proper error handling and no database interaction with malicious input📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed signup attempts with special characters
- Database query errors containing fname parameter
Network Indicators:
- HTTP POST requests to /signup.php containing SQL keywords (UNION, SELECT, etc.) in parameters
- Abnormal traffic patterns to registration endpoint
SIEM Query:
source="web_logs" AND uri_path="/signup.php" AND (param_fname CONTAINS "'" OR param_fname CONTAINS "--" OR param_fname CONTAINS "UNION")
