Dell SupportAssist OS Recovery, versions prior to 5.5.14.0, contain a Creation of Temporary File With Insecure Permissions vulnerability. A local authenticated attacker could potentially exploit this vulnerability, leading to Elevation of Privileges.

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:L, PR:L (acceso local autenticado) sin interacción → T1068. Archivo temporal inseguro permite escalada de privilegios (CWE-378). Impactos: elevación de privilegios mediante manipulación de permisos de archivos.

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.
