Detailsinfo

A vulnerability was found in IBM AIX up to 5.3 L (Operating System). It has been rated as critical. This issue affects an unknown code of the component muxatmd. 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 5.1, 5.2, and 5.3 allow remote attackers to execute arbitrary code via (1) muxatmd and (2) slocal.

The issue has been introduced in 05/01/2001. The weakness was released 12/15/2005 by David Litchfield with NGS Software (Website). The advisory is shared at securityfocus.com. The identification of this vulnerability is CVE-2005-4272 since 12/15/2005. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1689 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 65268 (AIX 5.3 TL 4 : bos.net.tcp.client (U800638)), 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 115416 (IBM AIX slocal and muxatmd Multiple Local Buffer Overflow Vulnerabilities).

Upgrading to version 6.1 eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (23637), Tenable (65268), SecurityFocus (BID 15879†), Secunia (SA18088†) and SecurityTracker (ID 1015366†).
