CVE-2025-48621

Estado: ModificadaAlta (7.3)—

In DefaultTransitionHandler.java, there is a possible way to enable a tapjacking attack due to a insecure default. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is 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.

Ataque tapjacking vía defecto inseguro en DefaultTransitionHandler; requiere interacción del usuario (UI:R) sobre Android local para escalar privilegios. Vector CVSS AV:L + UI:R → T1203. Escalación de privilegios (PR:L → admin/root) e acceso a datos sensibles (C:H/I: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.
