medium Nessus Plugin ID 102708
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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 denial of service vulnerability in the rpd daemon due to improper handling of MPLS ping packets. An unauthenticated, remote attacker can exploit this, via a specially crafted MPLS ping packet, to crash the rpd daemon.

Note that the device is only vulnerable if MPLS OAM is configured.

Solution

Upgrade to the relevant Junos software release referenced in Juniper security advisory JSA10795.
