🛠️ 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 workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize the ID parameter before processing in /friendsphoto.php
Modify friendsphoto.php to validate ID parameter as integer using is_numeric() or similar
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
Add WAF rule to block requests containing SQL keywords in ID parameter
🧯 If You Can't Patch
- Isolate the affected system from the internet and restrict access to internal networks only
- Implement strict network segmentation and monitor all database access attempts
🔍 How to Verify
Check if Vulnerable:
Test the /friendsphoto.php endpoint with SQL injection payloads in the ID parameterCheck Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and return appropriate error messages📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed parameter validation attempts
Network Indicators:
- HTTP requests to /friendsphoto.php with SQL keywords in parameters
- Unusual database query patterns
SIEM Query:
source="web_logs" AND uri="/friendsphoto.php" AND (param="ID" AND value MATCHES "(?i)(union|select|insert|delete|update|drop|alter)")
