🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor was contacted but did not respond. Consider workarounds or alternative software.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection rules to block malicious requests targeting the Type parameter.
Input Validation Filter
allImplement server-side input validation to sanitize the Type parameter before processing.
🧯 If You Can't Patch
- Isolate the affected system from the internet and restrict network access to only necessary connections.
- Implement strict monitoring and alerting for SQL injection attempts in application logs.
🔍 How to Verify
Check if Vulnerable:
Check if AMTT HiBOS version 1.0 is installed. Test the Type parameter with SQL injection payloads (use authorized testing only).Check Version:
Check application documentation or interface for version information. No standard command available.Verify Fix Applied:
Verify that SQL injection attempts on the Type parameter are properly blocked or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts or parameter manipulation attempts
Network Indicators:
- HTTP requests with SQL keywords in Type parameter (SELECT, UNION, INSERT, etc.)
- Unusual database connection patterns
SIEM Query:
Example: http.request.uri contains "Type=" AND (http.request.uri contains "SELECT" OR "UNION" OR "INSERT")
