🔍 How to Verify
Check if Vulnerable:
Check if unauthenticated requests to FetchStoredLicense endpoint return sensitive information. Monitor for unusual license-related API calls.Check Version:
Check Senstar Symphony version through web interface or installation directory propertiesVerify Fix Applied:
Verify patch version matches vendor recommendation and test that FetchStoredLicense endpoint no longer discloses sensitive information without authentication.📡 Detection & Monitoring
Log Indicators:
- Unusual access patterns to license-related endpoints
- Unauthenticated requests to FetchStoredLicense method
- Multiple failed authentication attempts followed by license API calls
Network Indicators:
- Unusual traffic to Senstar Symphony management ports from untrusted sources
- HTTP requests to FetchStoredLicense endpoint without authentication headers
SIEM Query:
source_ip NOT IN trusted_networks AND dest_port IN (80,443,management_ports) AND uri_path CONTAINS 'FetchStoredLicense'
