-A weakness could have allowed an authenticated Kiteworks Email Protection Gateway administrator to write a file outside its intended location and cause the application to execute it, potentially resulting in remote code execution as the underlying service account.

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.

Requiere autenticación administrativa (PR:H) en servicio remoto con acceso a red. Escritura de archivos fuera del directorio permitido (CWE-22) y ejecución posterior generan RCE como cuenta de servicio.

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.
