W3C Amaya 9.4 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, which was classified as critical, has been found in W3C Amaya 9.4. 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 World Wide Web Consortium (W3C) Amaya 9.4, and possibly other versions including 8.x before 8.8.5, allow remote attackers to execute arbitrary code via a long value in (1) the COMPACT attribute of the COLGROUP element, (2) the ROWS attribute of the TEXTAREA element, and (3) the COLOR attribute of the LEGEND element; and via other unspecified attack vectors consisting of "dozens of possible snippets."

The bug was discovered 12/21/2005. The weakness was published 04/12/2006 by Thomas Waldegger (Website). The advisory is shared at morph3us.org. The identification of this vulnerability is CVE-2006-1900 since 04/20/2006. The exploitation is known to be difficult. 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.

After immediately, there has been an exploit disclosed. The exploit is available at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 112 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 21520 (FreeBSD : amaya -- Attribute Value Buffer Overflow Vulnerabilities (dc930435-d59f-11da-8098-00123ffe8333)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks and running in the context l.

Upgrading to version 9.4 eliminates this vulnerability. A possible mitigation has been published 3 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (25791), Exploit-DB (27640), Tenable (21520), SecurityFocus (BID 17507†) and OSVDB (24623†). Similar entry is available at VDB-83793. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
