An improper verification of a loaded library in Zscaler Client Connector on Mac < 4.2.0.241 may allow a local attacker to elevate their privileges.

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 sin UI permite escalada local. CWE-346 (improper verification de library) sugiere secuestro de DLL/dylib. Impacto: obtención de privilegios elevados (T1548) vía manipulación de librerías cargadas (T1574.006).

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.
