Improper verification of access permissions when modifying permissions through the Administration Control Panel (ACP) allowed an authenticated administrator to grant permissions beyond the level authorized for their account, resulting in privilege escalation within the administrative interface.

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.

Vector PR:H (requiere privilegios de administrador) sugiere acceso a servicios remotos autenticados (T1210). El impacto principal es modificación de cuentas/permisos administrativos (T1098.002); secundariamente, escalada de privilegios dentro de la interfaz administrativa (T1068).

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.
