Descriptions

An issue was discovered in USBGuard before 1.1.0. On systems with the usbguard-dbus daemon running, an unprivileged user could make USBGuard allow all USB devices to be connected in the future.

Se ha detectado un problema en USBGuard versiones anteriores a 1.1.0. En sistemas con el demonio usbguard-dbus en ejecución, un usuario no privilegiado podía hacer que USBGuard permitiera la conexión de todos los dispositivos USB en el futuro

A flaw was found in usbguard. The vulnerability occurs due to the No default access control list(ACL) on some D-Bus methods and leads to unauthorized access. This flaw allows an attacker to access and escape policy configuration.
