Juniper Junos for M/MX Series Routers IPv6 Neighbor Discovery DoS (JSA10786)
Low Nessus Plugin ID 99527
SynopsisThe remote device is affected by a denial of service vulnerability.
DescriptionAccording 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.
