Summary

An exploitable authentication bypass vulnerability exists in the hostname processing of the Moxa AWK-3131A firmware version 1.13. A specially configured device hostname can cause the device to interpret select remote traffic as local traffic, resulting in a bypass of web authentication. An attacker can send authenticated SNMP requests to trigger this vulnerability.
