According to its self-reported version number, the remote Junos device is affected by a remote code execution vulnerability due to a lack of validation when passing input from the ‘rs’ parameter to the ‘/jsdm/ajax/port.php’ script. Authenticated users, when J-Web is enabled, can execute arbitrary commands with administrative privileges.
