Recommendation: Monitor — no exploitation signal at the moment.

A missing validation process exists in Serv U when abused, could give a malicious actor with access to admin privileges the ability to execute code. This issue requires administrative privileges to abuse. On Windows deployments, the risk is scored as a medium because services frequently run under less-privileged service accounts by default.
