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.

Technical ContextAI
CWE-704 (misclassified — actually IDOR). Attackers can access resources belonging to other users by manipulating object references.
