CVE-2025-48632

Estado: ModificadaAlta (7.8)—

In setDisplayName of AssociationRequest.java, there is a possible way to cause CDM associations to persist after the user has disassociated them due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

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.

Vulnerabilidad local (AV:L) con privilegios limitados (PR:L) sin interacción del usuario (UI:N) que escala privilegios mediante validación impropia de entrada en CDM, persistiendo asociaciones no autorizadas que resultan en acceso elevado a la cuenta del dispositivo.

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.
