Detailsinfo

A vulnerability has been found in Juniper Jnos up to 6.3 and classified as critical. Affected by this vulnerability is an unknown functionality of the component IPv6 Neighbor Discovery. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The IPv6 Neighbor Discovery Protocol (NDP) implementation in (1) FreeBSD 6.3 through 7.1, (2) OpenBSD 4.2 and 4.3, (3) NetBSD, (4) Force10 FTOS before E7.7.1.1, (5) Juniper JUNOS, and (6) Wind River VxWorks 5.x through 6.4 does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity) or read private network traffic via a spoofed message that modifies the Forward Information Base (FIB).

The weakness was released 10/03/2008 as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. This vulnerability is known as CVE-2008-2476 since 05/28/2008. The attack can be launched remotely. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 39001 (HP-UX PHNE_38680 : HP-UX Running IPv6, Remote Denial of Service (DoS) and Unauthorized Access (HPSBUX02407 SSRT080107 rev.1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family HP-UX Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 116191 (HP-UX Running IPv6, Remote Denial of Service Vulnerability (HPSBUX02407)).

Applying a patch is able to eliminate this problem. A possible mitigation has been published 5 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (45601), Tenable (39001), SecurityFocus (BID 31529†), OSVDB (48744†) and Secunia (SA32112†). Entries connected to this vulnerability are available at VDB-46293, VDB-44315, VDB-43997 and VDB-43942. Be aware that VulDB is the high quality source for vulnerability data.
