CVE-2025-40538 (GCVE-0-2025-40538)

Vulnerability from cvelistv5 – Published: 2026-02-24 07:40 – Updated: 2026-02-24 15:58

Title

SolarWinds Serv-U Broken Access Control Remote Code Execution Vulnerability

Summary

A broken access control vulnerability exists in Serv-U which when exploited, gives a malicious actor the ability to create a system admin user and execute arbitrary code as a privileged account via domain admin or group admin privileges. 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.

Severity ?

9.1 (Critical)
