IBM AIX up to 5.3.0 ICMP Error Message entropy

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, has been found in IBM AIX up to 5.3.0 (Operating System). This issue affects an unknown part of the component ICMP Error Message Handler. The manipulation with an unknown input leads to a entropy vulnerability. Using CWE to declare the problem leads to CWE-331. The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others. Impacted is availability. The summary by CVE is:

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.

The bug was discovered 07/30/2003. The weakness was released 04/13/2005 by Fernando Gont (Paul) as MS05-019 (Website). The advisory is shared at gont.com.ar. The identification of this vulnerability is CVE-2004-0230 since 03/17/2004. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.

The exploit is available at gont.com.ar. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 209 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 18023 (MS05-019: Vulnerabilities in TCP/IP Could Allow Remote Code Execution (893066)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows : Microsoft Bulletins and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 82054 (TCP Sequence Number Approximation Based Denial of Service).

Upgrading to version 6.1 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at aix.software.ibm.com.Addressing this vulnerability is possible by firewalling . The best possible mitigation is suggested to be applying a restrictive firewalling. A possible mitigation has been published even before and not after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 2523.

The vulnerability is also documented in the databases at X-Force (15886), Exploit-DB (276), Tenable (18023), SecurityFocus (BID 10183†) and OSVDB (4030†). Entries connected to this vulnerability are available at VDB-1268, VDB-1365, VDB-1364 and VDB-1359. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
