Description

A Missing Authorization vulnerability in the CLI of Juniper Networks Junos OS on MX Series allows a local, authenticated user with low privileges to execute specific commands which will lead to a complete compromise of managed devices. Any user logged in, without requiring specific privileges, can issue 'request csds' CLI operational commands.
