Vulnerability from fkie_nvd - Published: 2025-11-18 09:15 - Updated: 2026-10-07 21:10
Severity
9.1 (Critical) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
Summary
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.
