IBM AIX 5.2/5.3 memory corruption

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 5.2/5.3 (Operating System). This issue affects an unknown functionality. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Multiple buffer overflows in IBM AIX 5.2 and 5.3 allow local users in the system group to gain root privileges via unspecified vectors involving the (1) chpath, (2) rmpath, and (3) devinstall programs in bos.rte.methods.

The issue has been introduced in 10/01/2002. The weakness was presented 08/14/2007 (Website). The advisory is shared at secunia.com. The identification of this vulnerability is CVE-2007-4353 since 08/14/2007. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/23/2019). It is expected to see the exploit prices for this product decreasing in the near future.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1745 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 28943 (AIX 5.3 TL 6 : bos.rte.methods (U811914)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family AIX Local Security Checks and running in the context l.

A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (35971) and Tenable (28943). See 2474, 2490, 2568 and 2570 for similar entries.
