What is CVE-2017-11400?

An issue has been identified in the Belden Hirschmann Tofino Xenon Security Appliance prior to version 03.2.00. This vulnerability occurs due to an incomplete firmware signature, which permits a local attacker to install unauthorized firmware, potentially compromising the device.
