Descriptions

An issue has been discovered on the Belden Hirschmann Tofino Xenon Security Appliance before 03.2.00. An incomplete firmware signature allows a local attacker to upgrade the equipment (kernel, file system) with unsigned, attacker-controlled, data. This occurs because the appliance_config file is signed but the .tar.sec file is unsigned.

Se ha descubierto un problema en las versiones anteriores a la 03.2.00 de Belden Hirschmann Tofino Xenon Security Appliance. Una firma incompleta del firmware permite que un atacante local actualice el equipamiento (kernel, sistema de archivo) con datos no firmados controlados por el atacante. Esto ocurre debido a que el archivo appliance_config está firmado, pero el archivo .tar.sec no lo está.
