🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - No official patch from vendor identified
Vendor Advisory: No vendor advisory found
Restart Required: No
Instructions:
1. Upgrade to a newer version if available from vendor
2. If no upgrade available, manually patch the news-detail.php file
3. Replace direct SQL concatenation with parameterized queries
4. Implement proper input validation for the newid parameter
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to ensure newid parameter contains only numeric values
In news-detail.php, add: if(!is_numeric($_GET['newid'])) { die('Invalid input'); }
WAF Rule
allImplement web application firewall rules to block SQL injection patterns
ModSecurity rule: SecRule ARGS:newid "@rx (?i)(union|select|insert|update|delete|drop|--|#|\/\*|\*\/)" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
Cloudflare WAF: Enable SQLi protection
🧯 If You Can't Patch
- Block external access to news-detail.php using firewall rules or .htaccess restrictions
- Implement database user with minimal permissions (read-only if possible) for the application
🔍 How to Verify
Check if Vulnerable:
Test by accessing news-detail.php with SQL injection payload: http://target.com/news-detail.php?newid=1' OR '1'='1Check Version:
Check MLM Forced Matrix version in admin panel or configuration filesVerify Fix Applied:
Attempt SQL injection payloads and verify they are rejected or sanitized without executing SQL commands📡 Detection & Monitoring
