🔍 How to Verify
Check if Vulnerable:
Check the StoneFly Storage Concentrator version via the web interface or CLI. If version is below 8.0.4.26, the system is vulnerable.Check Version:
ssh admin@storage-concentrator-ip 'show version' or check via web interface System > AboutVerify Fix Applied:
After patching, verify the version shows 8.0.4.26 or higher and test that directory traversal attempts via the Online Help path parameter are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual path patterns in Online Help access logs containing '../' or similar traversal sequences
