CVE-2025-40541: SolarWinds Serv-U

High severity, CVSS 7.2. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• SolarWinds Serv-U: before 15.5.4 (fixed in 15.5.4)
