IBM AIX 6.1/7.1 ibstat privileges management

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.

A vulnerability, which was classified as critical, has been found in IBM AIX 6.1/7.1 (Operating System). Affected by this issue is the function ibstat. The manipulation with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Multiple unspecified vulnerabilities in the InfiniBand subsystem in IBM AIX 6.1 and 7.1, and VIOS 2.2.2.2-FP-26 SP-02, allow local users to gain privileges via vectors involving (1) arp.ib or (2) ibstat.

The issue has been introduced in 11/09/2007. The weakness was presented 07/16/2013 as confirmed advisory (Website). The advisory is available at aix.software.ibm.com. This vulnerability is handled as CVE-2013-4011 since 06/07/2013. The exploitation is known to be easy. Local access is required to approach this attack. No form of authentication is required for exploitation. Technical details as well as a public exploit are known. This vulnerability is assigned to T1068 by the MITRE ATT&CK project.

A public exploit has been developed by Kristian Erik Hermansen and been published 4 days after the advisory. The exploit is available at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2076 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 69287 (AIX 7.1 TL 2 : devices.common.IBM.ib.rte (U857552)), 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 121337 (IBM AIX InfiniBand Local Privilege Escalation Vulnerability).

Applying the patch 7.1.2.2 is able to eliminate this problem. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (85617), Exploit-DB (28507), Tenable (69287), SecurityFocus (BID 61287†) and OSVDB (95420†). See VDB-9577 for similar entry.
