critical Nessus Plugin ID 102706
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 remote code execution vulnerability in the snmpd daemon due to improper handling of SNMP packets. An unauthenticated, remote attacker can exploit this, via a specially crafted SNMP packet, to cause a denial of service condition or the execution of arbitrary code..

Solution

Upgrade to the relevant Junos software release referenced in Juniper security advisory JSA10793. Alternatively, as a workaround, disable the SNMP service.
