IBM AIX 6.1/7.1 Runtime Linker malloc MALLOCOPTIONS/MALLOCBUCKETS access control

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, was found in IBM AIX 6.1/7.1 (Operating System). This affects the function malloc of the component Runtime Linker. The manipulation of the argument MALLOCOPTIONS/MALLOCBUCKETS as part of a Environment Variable leads to a access control vulnerability. CWE is classifying the issue as CWE-264. This is going to have an impact on confidentiality, integrity, and availability.

The issue has been introduced in 11/09/2007. The weakness was presented 07/01/2014 by Tim Brown (Portcullis) with Portcullis Computer Security Ltd. as AIX Malloc vulnerability as confirmed advisory (Website). It is possible to read the advisory at aix.software.ibm.com. This vulnerability is uniquely identified as CVE-2014-3074 since 04/29/2014. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details and a public exploit are known. The attack technique deployed by this issue is T1068 according to MITRE ATT&CK.

A public exploit has been developed by Hector X. Monsegur and been published 3 years after the advisory. The exploit is shared for download 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 2426 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 77261 (AIX 6.1 TL 7 : malloc (IV62802)), 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 122216 (IBM AIX Malloc Privilege Escalation Vulnerability).
