IBM Informix Dynamic Server 9.40.xc8 denial of service

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 problematic, was found in IBM Informix Dynamic Server 9.40.xc8 (Information Management Software). This affects an unknown functionality. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on confidentiality. The summary by CVE is:

IBM Informix Dynamic Server (IDS) before 9.40.xC8 and 10.00 before 10.00.xC4 stores passwords in plaintext in shared memory, which allows local users to obtain passwords by reading the memory (product defects 171893, 171894, 173772).

The bug was discovered 01/06/2005. The weakness was presented 08/08/2006 by David Litchfield with Next Generation Security Software (Website). It is possible to read the advisory at www-1.ibm.com. This vulnerability is uniquely identified as CVE-2006-3858 since 07/26/2006. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 572 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 22229 (Informix Dynamic Server Multiple Remote Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gain a shell remotely and running in the context r.

It is possible to mitigate the problem by adding an authentication mechanism. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 4710.

The vulnerability is also documented in the databases at X-Force (28132), Tenable (22229), SecurityFocus (BID 19264†), OSVDB (27691†) and Secunia (SA21301†).
