CVE-2026-59568

Estado: Pendiente de análisisCrítica (9.1)—

Multiple vulnerabilities on affected versions of Zscaler Client Connector allow remote code execution, giving an unauthenticated, unprivileged user the ability to execute arbitrary code in the ZCC context.

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.

Vector CVSS AV:N/PR:N/UI:N indica exposición remota sin privilegios ni interacción (T1190). RCE explícito permite ejecución de código arbitrario (T1059). Acceso no autenticado implica potencial obtención de contexto de usuario ZCC (T1078).

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.
