CVE-2025-27703

Estado: AnalizadaAlta (7)—

CVE-2025-27703 is a privilege escalation vulnerability in the management console of Absolute Secure Access prior to version 13.54. Attackers with administrative access to a specific subset of privileged features in the console can elevate their permissions to access additional features in the console. The attack complexity is low, there are no preexisting attack requirements; the privileges required are high, and there is no user interaction required. The impact to system confidentiality is low, the impact to system integrity is high and the impact to system availability is low.

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 AV:N con PR:H indica acceso remoto con privilegios elevados previos. La escalada de permisos intra-aplicación hacia 'additional features' es T1068 por impacto de integridad (VI:H).

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.
