Description

An Insecure Direct Object Reference (IDOR) vulnerability exists in Serv-U, which when exploited, gives a malicious actor the ability to execute native code as a privileged account. 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.
