      "value": "AGL app-framework-binder (afb-daemon) through v19.90.0 allows any local process to execute privileged supervision commands (Exit, Do, Sclose, Config, Trace, Debug, Token, slist) without authentication via the abstract Unix socket @urn:AGL:afs:supervision:socket. The on_supervision_call function in src/afb-supervision.c dispatches all 8 commands without any credential verification. The abstract socket has no DAC protection, as acknowledged in the official CAUTION comment in src/afs-supervision.h. This allows a low-privileged local process to kill the daemon (DoS via Exit command), execute arbitrary API calls (via Do command), close arbitrary user sessions (via Sclose command), or leak the entire global configuration (via Config command). The vulnerability was introduced in commit b8c9d5de384efcfa53ebdb3f0053d7b3723777e1 on 2017-06-29."

      "value": "AGL app-framework-binder (afb-daemon) hasta la v19.90.0 permite a cualquier proceso local ejecutar comandos de supervisión privilegiados (Exit, Do, Sclose, Config, Trace, Debug, Token, slist) sin autenticación a través del socket Unix abstracto @urn:AGL:afs:supervision:socket. La función on_supervision_call en src/afb-supervision.c despacha los 8 comandos sin ninguna verificación de credenciales. El socket abstracto no tiene protección DAC, como se reconoce en el comentario oficial CAUTION en src/afs-supervision.h. Esto permite a un proceso local con pocos privilegios matar el demonio (DoS a través del comando Exit), ejecutar llamadas API arbitrarias (a través del comando Do), cerrar sesiones de usuario arbitrarias (a través del comando Sclose) o filtrar la configuración global completa (a través del comando Config). La vulnerabilidad fue introducida en el commit b8c9d5de384efcfa53ebdb3f0053d7b3723777e1 el 29-06-2017."
