🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and parameterized queries in profile.php.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to only accept numeric values for mobilenumber parameter
Edit profile.php to add: if(!is_numeric($_POST['mobilenumber'])) { die('Invalid input'); }
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
ModSecurity rule: SecRule ARGS:mobilenumber "@detectSQLi" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from application server only
🔍 How to Verify
Check if Vulnerable:
Test profile.php endpoint with SQL injection payloads in mobilenumber parameter: ' OR '1'='1Check Version:
Check application version in admin panel or readme filesVerify Fix Applied:
Test with same payloads after implementing fixes - should return error or sanitized response📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in PHP logs
- Multiple rapid requests to profile.php with special characters
- Database connection errors
Network Indicators:
- HTTP POST requests to /profile.php containing SQL keywords in parameters
- Unusual database traffic patterns from web server
SIEM Query:
source="web_logs" AND uri="/profile.php" AND (param="mobilenumber" AND value MATCHES "(?i)(union|select|insert|delete|update|drop|--|#|;)")
