CVE-2025-11957

Estado: ModificadaCrítica (9)—

Improper authorization in the temporary access workflow of Devolutions Server 2025.2.12.0 and earlier allows an authenticated basic user to self-approve or approve the temporary access requests of other users and gain unauthorized access to vaults and entries via crafted API requests.

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.

Autenticación requerida (PR:L) permite aprovechamiento de flujo de autorización deficiente en API remota para obtener acceso no autorizado a bóvedas y entradas de otros usuarios mediante solicitudes manipuladas.

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.
