Description

A logic error vulnerability exists in Serv-U which 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.
