What it is

A Missing Authorization vulnerability in the CLI of Juniper Networks Junos OS and Junos OS Evolved allows a local user with low privileges to read sensitive information.

A local user with low privileges can execute the CLI command 'show mgd' with specific arguments which will expose sensitive information.
