CVE-2024-53694

Estado: AplazadaAlta (8.6)—

A time-of-check time-of-use (TOCTOU) race condition vulnerability has been reported to affect several product versions. If exploited, the vulnerability could allow local attackers who have gained user access to gain access to otherwise unauthorized resources.

We have already fixed the vulnerability in the following versions: QVPN Device Client for Mac 2.2.5 and later Qsync for Mac 5.1.3 and later Qfinder Pro Mac 7.11.1 and later

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.

TOCTOU con UI:R en acceso local indica ejecución en cliente por interacción. El CWE-367 permite acceso a recursos no autorizados, sugestivo de escalada de privilegios.

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.
