IBM AIX 6.1/7.1 IPv6 Packet 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, which was classified as critical, has been found in IBM AIX 6.1/7.1 (Operating System). This issue affects some unknown functionality of the component IPv6 Packet Handler. 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 integrity, and availability. The summary by CVE is:

The IPv6 implementation in the inet subsystem in IBM AIX 6.1 and 7.1, and VIOS 2.2.2.2-FP-26 SP-02, allows remote attackers to cause a denial of service (system hang) via a crafted packet to an IPv6 interface.

The issue has been introduced in 11/09/2007. The weakness was released 06/04/2013 as inet_advisory.asc as confirmed advisory (Website). It is possible to read the advisory at aix.software.ibm.com. The identification of this vulnerability is CVE-2013-3035 since 04/12/2013. 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 2034 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 71164 (AIX 6.1 TL 9 : bos.net.tcp.client (U855283)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family AIX Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 121253 (IBM AIX Inet Denial of Service Vulnerability).

Addressing this vulnerability is possible by firewalling IPv6. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (84657), Tenable (71164), SecurityFocus (BID 60348†), OSVDB (93951†) and Secunia (SA53687†). www-01.ibm.com is providing further details. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
