Juniper Products Neighbor Discovery Protocol Neighbor Solicitation Vulnerability

-

Description


A vulnerability has been reported in multiple Juniper Networks products, which can be exploited by malicious people to manipulate the router's neighbor cache.

The vulnerability is caused due to an error in the implementation of the Neighbor Discovery protocol when processing neighbor solicitation requests. This can be exploited to add a fake entry to the router's neighbor cache via a neighbor solicitation request containing a spoofed IPv6 address.

Successful exploitation may allow the interception or disruption of network traffic, but requires that the IPv6 nodes involved in the attack are using the same router.

NOTE: The vendor has not published a publicly available advisory and has also refused to provide a list of the affected products or patches as information about vulnerabilities is provided to registered customers only. It is therefore unclear if only a subset of the products reported as vulnerable in this advisory are affected.


Solution:
It is currently unclear whether fixes are available.
