CVE-2025-41246

Estado: AplazadaAlta (7.6)—

VMware Tools for Windows contains an improper authorisation vulnerability due to the way it handles user access controls. A malicious actor with non-administrative privileges on a guest VM, who is already authenticated through vCenter or ESX may exploit this issue to access other guest VMs. Successful exploitation requires knowledge of credentials of the targeted VMs and vCenter or ESX.

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:A y PR:H indican red adyacente con privilegios previos (acceso autenticado a vCenter/ESX). Acceso a otras VMs guest con credenciales conocidas es lateral movement (T1210). Impacto: obtener acceso válido a cuentas (T1078) y conexión remota a sistemas (T1021.002).

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.
