Missing bounds check in the annotator function of Zoom Clients allows buffer over-write, which may allow a meeting participant to achieve remote code execution of another participant via network access.

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 UI:R (interacción requerida) + buffer overflow en función anotadora de cliente → ejecución remota de código en cliente. La vulnerabilidad requiere que el usuario participe en la reunión, típico de T1203 (explotación para ejecución en cliente).

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.
