Problem

An Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the User Interface (UI) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged, authenticated attacker with access to the CLI to access sensitive information.

Through the execution of a specific show mgd command, a user with limited permissions (e.g., a low-privileged login class user) can access sensitive information such as hashed passwords, that can be used to further impact the system.
