CVE-2023-21343

Estado: ModificadaAlta (7.8)—

En ActivityStarter, existe un posible inicio de actividad en segundo plano debido a un PendingIntent inseguro. Esto podría conducir a una escalada local de privilegios sin necesidad de permisos de ejecución adicionales. La interacción del usuario no es necesaria para la explotación.

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).
