Estado: AplazadaCrítica (9.1)—

An issue was discovered in TitanHQ SpamTitan Email Security Gateway 8.00.x before 8.00.101 and 8.01.x before 8.01.14. The file quarantine.php within the SpamTitan interface allows unauthenticated users to trigger account-level actions using a crafted GET request. Notably, when a non-existent email address is provided as part of the email parameter, SpamTitan will automatically create a user record and associate quarantine settings with it - all without requiring authentication.

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/PR:N/UI:N permite acceso remoto sin autenticación a quarantine.php (T1190). La creación automática de cuentas de usuario sin autenticación (T1078, T1136) permite acceso no autorizado a la puerta de enlace de seguridad de correo.

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.
