HTTP: Microsoft WebDAV XML Message Handler Denial of Service

This signature detects denial-of-service (DoS) attempts against the WebDAV XML Message Handler in Microsoft IIS. Attackers can send a malicious HTTP request to a WebDAV enabled IIS server to cause it to consume all system resources. A machine reboot is required to resume service.

Extended Description

Microsoft XML Parser is prone to a remote denial of service vulnerability when handling malformed requests. The vulnerability can be exploited through the WebDAV XML message handler of Microsoft IIS server. It is reported that this issue requires a remote attacker to create specially crafted WebDAV requests and send them to a vulnerable server over TCP port 80. There is a possibility of increased CPU resource and memory consumption as the IIS server attempts to process these requests. This can eventually lead to a denial of service condition in the server. A reboot is required to restore normal functionality. This vulnerability can also be exposed through other applications that rely on Microsoft XML Parser to process XML messages.
