IBM AIX 5.3 syscall 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.

Detailsinfo

A vulnerability classified as critical has been found in IBM AIX 5.3 (Operating System). This affects the function syscall. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in the syscall implementation in IBM AIX 5.3 allows local users to gain privileges via unspecified vectors.

The issue has been introduced in 08/01/2004. The weakness was shared 07/07/2009 (Website). The advisory is shared at www-01.ibm.com. This vulnerability is uniquely identified as CVE-2009-2434 since 07/13/2009. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 08/12/2021). It is expected to see the exploit prices for this product decreasing in the near future.

The vulnerability was handled as a non-public zero-day exploit for at least 1801 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 65420 (AIX 5.3 TL 11 : bos.rte.shell (U820270)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family AIX Local Security Checks.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (51612), Tenable (65420), SecurityFocus (BID 35615†), OSVDB (55727†) and Secunia (SA35754†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
