Microsoft IIS 5.x and 6.0 suffer from a denial of service vulnerability regarding the WebDAV XML parser. An attacker can craft a malicious WebDAV PROPFIND request, which uses XML attributes in a way that inflicts a denial of service condition on the target machine (IIS web server). The result of this attack is that the XML parser consumes all the CPU resources for a long period of time (from seconds to minutes, depending on the size of the payload).

--[ Author: Amit Klein

--[ Release Date: October 12, 2004

--[ Products:

Microsoft IIS/5.0 (Windows/2000)
Microsoft IIS/5.1 (Windows XP)
Microsoft IIS/6.0 (Windows/2003)

--[ Severity: High

--[ Description

An attacker can craft a malicious WebDAV PROPFIND request, which
uses XML attributes in a way that inflicts a denial of service
condition on the target machine (IIS web server).
The result of this attack is that the XML parser consumes all the
CPU resources for a long period of time (from seconds to minutes,
depending on the size of the payload). In our experiments, we were
able to send attacks (of few hunderd KBs) that caused the target
machines to consume 100% CPU for several minutes.

attack to IIS.
