CVE-2026-40145

Estado: Pendiente de análisisAlta (7.1)—

A vulnerability exists in the interaction between a Endpoint Privilege Management (Windows Deployment) support utility and the agent's tamper protection controls. Under certain conditions, the protections applied to the utility process may not be enforced as intended.

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:L/PR:H sin UI:R indica escalada local; vulnerabilidad en utilidad de gestión de privilegios (Endpoint Privilege Management) que no aplica protecciones de integridad esperadas, permitiendo evasión de controles de tampering.

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.
