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. These commands are only meant to be executed by high privileged or users designated for Juniper Device Manager (JDM) / Connected Security Distributed Services (CSDS) operations as they will impact all aspects of the devices managed via the respective MX. This issue affects Junos OS on MX Series: * 24.4 releases before 24.4R2-S3, * 25.2 releases before 25.2R2. This issue does not affect Junos OS releases before 24.4.
