CVE-2026-40141

Estado: AnalizadaAlta (8.5)—

A high-severity vulnerability exists in a web application component of BeyondTrust Remote Support and Privileged Remote Access related to the processing of certain input parameters. Insufficient validation of user-supplied input may allow an authenticated attacker with limited privileges to access unintended resources or data beyond their authorization scope. Exploitation is restricted to accounts with specific permissions.

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/PR:L requiere red y privilegios; acceso a recursos no autorizados (T1005) por validación insuficiente de parámetros; escalada dentro del sistema de cuenta autenticada (T1078.001).

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.
