CVE-2023-20911

Estado: ModificadaAlta (7.8)—💥 PoC

En addPermission de PermissionManagerServiceImpl.java, existe un posible fallo al persistir la configuración de permisos debido al agotamiento de recursos. Esto podría derivar en una escalada de privilegios local sin que se necesiten privilegios de ejecución adicionales. No es necesaria la interacción del usuario para la explotación.Product: Android Versions: Android-11 Android-12 Android-12L Android-13 Android ID: A-242537498

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
