🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
1. Review the vulnerable code in /admin/password-recovery.php
2. Implement proper input validation and parameterized queries
3. Sanitize username parameter before database interaction
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to reject suspicious characters in username parameter
Add to password-recovery.php: if(preg_match('/[\'"\;\-\#\*]/', $_POST['username'])) { die('Invalid input'); }
File Access Restriction
allRestrict access to vulnerable file via web server configuration
Apache: <Location "/admin/password-recovery.php">
Order deny,allow
Deny from all
</Location>
Nginx: location ~ /admin/password-recovery\.php$ { return 403; }
🧯 If You Can't Patch
- Implement web application firewall (WAF) with SQL injection rules
- Restrict network access to the application to trusted IPs only
🔍 How to Verify
Check if Vulnerable:
Test username parameter with SQL injection payloads like ' OR '1'='1 in password recovery formCheck Version:
Check software version in admin panel or readme filesVerify Fix Applied:
Verify parameterized queries are used and input validation rejects SQL injection attempts📡 Detection & Monitoring
