The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in the Plug and Play (PnP) service (UMPNPMGR.DLL) in Microsoft Windows 2000 SP4, and XP SP1 and SP2, allows remote or local authenticated attackers to execute arbitrary code via a large number of "\" (backslash) characters in a registry key name, which triggers the overflow in a wsprintfW function call.

The bug was discovered 10/11/2005. The weakness was shared 10/11/2005 by Derek Soeder with eEye Digital Security as MS05-047 as confirmed bulletin (Technet). The advisory is shared at microsoft.com. This vulnerability is known as CVE-2005-2120 since 07/02/2005. The attack can be launched remotely. A single authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

After 2 weeks, there has been an exploit disclosed. It is possible to download the exploit at securiteam.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 2010 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 20000 (MS05-047: Vulnerability in Plug and Play Could Allow Remote Code Execution and Local Elevation of Privilege (905749)), which helps to determine the existence of the flaw in a target environment.
