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.

An issue has been discovered on the Belden Hirschmann Tofino Xenon Security Appliance before 03.2.00. Improper handling of the mbap.length field of ModBus packets in the ModBus DPI filter allows an attacker to send malformed/crafted packets to a protected asset, bypassing function code filtering.

An issue has been discovered on the Belden Hirschmann Tofino Xenon Security Appliance before 03.2.00. Design flaws in OPC classic and in custom netfilter modules allow an attacker to remotely activate rules on the firewall and to connect to any TCP port of a protected asset, thus bypassing the firewall. The attack methodology is a crafted OPC dynamic port shift.
