No official patch available. Consider workarounds or migrating to alternative software.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize U_USERNAME parameter before processing
Edit LogSignModal.PHP to add parameter sanitization using prepared statements or input filtering
Web Application Firewall
allDeploy WAF rules to block SQL injection patterns
Configure WAF to block requests containing SQL injection patterns in parameters
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement network segmentation to limit database access from the web application
🔍 How to Verify
Check if Vulnerable:
Test the U_USERNAME parameter in LogSignModal.PHP with SQL injection payloads like ' OR '1'='1Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Test with the same payloads after applying workarounds to ensure they are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts with SQL patterns
- Requests to LogSignModal.PHP with suspicious parameters
Network Indicators:
- HTTP requests containing SQL keywords in U_USERNAME parameter
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/LogSignModal.PHP" AND (param="U_USERNAME" AND value MATCHES "(?i)(union|select|insert|update|delete|drop|or|and|'|--|#)")
