Juniper Junos Local Privilege Escalation Vulnerability (JSA69725)

high Nessus Plugin ID 163461

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

An Improper Neutralization of Special Elements vulnerability in the download manager of Juniper Networks Junos OS allows a locally authenticated attacker with low privileges to take full control over the device.
A workaround would be to deny users access to the 'request system download ...' and 'show system download ...' CLI commands.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
