Summary

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.

Exploit prediction (EPSS)

0.27% probability of exploitation in the next 30 days, higher than 20% of all scored CVEs.
