CVE-2025-8853

Estado: AplazadaCrítica (9.3)—

Official Document Management System developed by 2100 Technology has an Authentication Bypass vulnerability, allowing unauthenticated remote attackers to obtain any user's connection token and use it to log into the system as that user.

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 explotación remota sin privilegios (T1190). Bypass de autenticación y robo de tokens otorgan acceso con credenciales válidas (T1078) y posible control de cuentas (T1556).

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.
