CVE-2023-20943

Estado: ModificadaAlta (7.8)—💥 PoC

En clearApplicationUserData de ActivityManagerService.java, existe una posible forma de eliminar archivos del sistema debido a un error de recorrido de rutas (path traversal). Esto podría provocar una escalada local de privilegios con privilegios de ejecución de usuario necesarios. No se necesita interacción del usuario para la explotación.Product: AndroidVersions: Android-10 Android-11 Android-12 Android-12L Android-13Android ID: A-240267890

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.
