Summary
A server-side request forgery (SSRF) vulnerability in WatchGuard Dimension Email Server Test configuration allows an authenticated privileged attacker to enumerate exposed network services on adjacent network systems.
Risk Assessment
The risk is the ability to probe the internal network and discover vulnerable services, which could facilitate further attacks. Attackers could also exploit this vulnerability to access internal resources.
Recommendation
It is recommended to update WatchGuard Dimension to the latest version that includes the fix. Also, restrict access to test functions and monitor network traffic for unusual requests.
