TITLE

GE MU320E Privilege Escalation Vulnerability

Trust: 0.6

sources: CNVD: CNVD-2021-24023

DESCRIPTION

A miscommunication in the file system allows adversaries with access to the MU320E to escalate privileges 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. GE MU320E 04A00.1 firmware has a privilege escalation vulnerability. The vulnerability stems from a communication error in the file system. Attackers can use this vulnerability to elevate permissions. GE MU320E could allow a local authenticated malicious user to gain elevated privileges on the system, caused by a miscommunication flaw in the file system. By sending a specially-crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges
