CVE-2025-58386

Estado: AnalizadaCrítica (9.8)—

In Terminalfour 8 through 8.4.1.1, the userLevel parameter in the user management function is not subject to proper server-side authorization checks. A Power User can intercept and modify this parameter to assign the Administrator role to other existing lower-privileged accounts, or invite a new lower-privileged account and escalate its privileges. While manipulating this request, the Power User can also change the target account's password, effectively taking full control of it.

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.

Explotación remota sin autenticación (PR:N, UI:N) de función de gestión de usuarios. El atacante escala privilegios ajenos (T1098.002), obtiene acceso como admin (T1078.001) y crea cuentas elevadas (T1136.003) modificando parámetro userLevel.

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.
