Microsoft Windows 2000 TCP Packet memory allocation

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 was found in Microsoft Windows 2000 (Operating System) and classified as problematic. This issue affects an unknown function of the component TCP Packet Handler. The manipulation with an unknown input leads to a memory allocation vulnerability. Using CWE to declare the problem leads to CWE-789. The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated. Impacted is availability. The summary by CVE is:

Microsoft Windows 2000 allows remote attackers to cause a denial of service (memory consumption) by sending a flood of empty TCP/IP packets with the ACK and FIN bits set to the NetBIOS port (TCP/139), as demonstrated by stream3.

The issue has been introduced in 02/17/2000. The weakness was published 12/31/2002 by 3APA3A with Microsoft (Website). It is possible to read the advisory at online.securityfocus.com. The identification of this vulnerability is CVE-2002-1712 since 06/21/2005. The exploitation is known to be easy. 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.

A public exploit has been developed in ANSI C. The exploit is available at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1048 days. During that time the estimated underground price was around $25k-$100k.
