CVE-2026-102146

Estado: En análisisMedia (6.5)—

An authenticated Email Protection Gateway administrator holding only limited, delegated permissions could write files with attacker-controlled content to arbitrary locations accessible to the Email Protection Gateway service account. This exceeds the administrator's intended privileges and could be used to alter application files and configuration or to disrupt the availability of the service.

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:N con PR:H (authenticated, admin delegado) + acceso a servicios remotos del gateway. Escritura de archivos arbitrarios permite manipulación de configuración (T1565.001) o DoS (T1499.004). Confianza T1210 moderada por contexto de privilegios autenticados en servicio remoto.

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.
