New! Plugin Severity Now Using CVSS v3

Synopsis

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

Description

According to its self-reported version number and configuration, the remote Juniper Junos device is affected by a privilege escalation vulnerability when running in a virtualized environment due to improper handling of authentication. An attacker on the Junos guest can exploit this to escalate privileges and gain access to the host operating system.

Solution

Upgrade to the relevant Junos software release referenced in Juniper security advisory JSA10787. Alternatively, as a workaround, enable FIPS mode.
