IBM zSeries IPv6 Neighbor Discovery input validation

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in IBM zSeries (unknown version). It has been rated as critical. This issue affects an unknown code block of the component IPv6 Neighbor Discovery. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The IPv6 Neighbor Discovery Protocol (NDP) implementation on IBM zSeries servers 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), a related issue to CVE-2008-2476.

The bug was discovered 10/02/2008. The weakness was published 10/03/2008 as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. The identification of this vulnerability is CVE-2008-4404 since 10/03/2008. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 35642 (HP-UX PHNE_37897 : 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 (35642), SecurityFocus (BID 31529†), OSVDB (48991†) and Vulnerability Center (SBV-19674†). Similar entries are available at VDB-46293 and VDB-44311. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
