Estado: AnalizadaAlta (8.8)—

An improper certificate validation vulnerability in Ivanti Secure Access Client before 22.8R6 allows a remote unauthenticated attacker to execute arbitrary code.

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.

CWE-295 (improper certificate validation) + UI:R + cliente Ivanti permiten ataque MITM (T1557) que ejecuta código arbitrario (T1059) mediante interacción del usuario con cliente vulnerable.

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.
