Summary

NoMachine nxhtd contains a Server-Side Request Forgery information disclosure vulnerability. This vulnerability allows remote attackers to initiate arbitrary server-side requests on affected installations of NoMachine without authentication. The flaw exists within the web service listening on UDP port 4443 by default and results from the lack of proper validation of a URI prior to accessing resources.

Risk Assessment

An unauthenticated attacker can use the server as a proxy for requests to internal resources, potentially leading to disclosure of internal network information.

Recommendation

Upgrade NoMachine to a version containing the fix and restrict access to UDP port 4443 from untrusted networks.
