CVE-2025-40547

Estado: AnalizadaCrítica (9.1)—

A logic error vulnerability exists in Serv-U which 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.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
Puntuación base: 9.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.89%
Percentil entre todas las CVEs puntuadas: 58
Fecha de la puntuación: 6/10/2026

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
