VAR-201711-0697

Vulnerability from variot - Updated: 2023-12-18 12:57

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. Belden Hirschmann Tofino Xenon Security Appliance Contains a data processing vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. ModBus DPI filter is one of the filters. The vulnerability stems from the fact that the program does not correctly process the mbap.length field of ModBus packets
