Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider implementing parameterized queries or input validation in review_result.php.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize mainevent_id parameter before processing
Modify review_result.php to validate mainevent_id as integer using filter_var($mainevent_id, FILTER_VALIDATE_INT)
Web Application Firewall Rule
allBlock SQL injection patterns in requests to review_result.php
Add WAF rule to detect and block SQL injection patterns in GET parameters
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all database access attempts
🔍 How to Verify
Check if Vulnerable:
Test review_result.php endpoint with SQL injection payloads like ' OR '1'='1 in mainevent_id parameterCheck Version:
Check application version in source code or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return error or sanitized response📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts after SQL injection attempts
- Database queries with unusual patterns
Network Indicators:
- HTTP requests to review_result.php with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/php-jms/review_result.php" AND (param="mainevent_id" AND value MATCH "('|\"|OR|AND|SELECT|UNION)")
