VAR-202103-0915

Vulnerability from variot - Updated: 2023-12-18 12:42

The software contains a hard-coded password that could allow an attacker to take control of the merging unit using these hard-coded credentials on the MU320E (all firmware versions prior to v04A00.1). MU320E is a process interface unit with integrated analog and digital combined interface introduced by GE.

The firmware of GE MU320E 04A00.1 earlier has a hard-coded password vulnerability. Attackers can use this vulnerability to control the merge unit
