CVE-2025-40549

Estado: AnalizadaCrítica (9.1)—

A Path Restriction Bypass vulnerability exists in Serv-U that when abused, could give a malicious actor with access to admin privileges the ability to execute code on a directory.

This issue requires administrative privileges to abuse. On Windows systems, this scored as medium due to differences in how paths and home directories are handled.

CVSS

Probabilidad de explotación (EPSS)

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N con PR:H indica acceso remoto con privilegios administrativos (T1210). La evasión de restricción de ruta (CWE-22) permite lectura de datos (T1005) y potencial ejecución de código en directorios (T1059).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
