Juniper Junos for M/MX Series Routers IPv6 Neighbor Discovery DoS (JSA10786)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote device is affected by a denial of service vulnerability.

Description :

According to its self-reported version and configuration, the remote
Juniper Junos M/MX Series device is affected by a denial of service
vulnerability in a Packet Forwarding Engine (PFE) when processing IPv6
neighbor discovery (ND) packets that originate from subscribers and
are destined to M/MX series routers that are configured with Enhanced
Subscriber Management for DHCPv6 subscribers. An unauthenticated,
adjacent attacker can exploit this to cause the PFE to hang or crash.
Note that this issue only affects devices whose system configuration
contains 'subscriber-management enable force'. Furthermore, devices
with only IPv4 configured are not affected.

Nessus has not tested for this issue but has instead relied only on
the device's self-reported version and current configuration.
