CVE-2025-65318

Estado: ModificadaCrítica (9.1)—

When using the attachment interaction functionality, Canary Mail 5.1.40 and below saves documents to a file system without a Mark-of-the-Web tag, which allows attackers to bypass the built-in file protection mechanisms of both Windows OS and third-party software.

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/AC:L/PR:N indica explotación remota sin privilegios (T1190). La falta de Mark-of-the-Web permite bypass de protecciones en adjuntos descargados (T1566.001) que ejecutan código malicioso localmente (T1204.001).

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.
