CVE-2023-20955

Estado: ModificadaAlta (7.8)—💥 PoC

En onPrepareOptionsMenu de AppInfoDashboardFragment.java, existe una posible forma de eludir las restricciones de administrador y desinstalar aplicaciones para todos los usuarios debido a una comprobación de permisos ausente. Esto podría dar lugar a una escalada de privilegios local sin que se necesiten privilegios de ejecución adicionales. No se necesita interacción del usuario para la explotación.Product: AndroidVersions: Android-11 Android-12 Android-12L Android-13Android ID: A-258653813

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.
