Description
Windows Scripting Host (WSH) is installed under either a Typical or Custom installation option of a Microsoft Network Server. This technology permits the execution of powerful script files from the Windows NT command line. This technology is also classified as a Category I Mobile Code. If the access to these files is not tightly controlled, a malicious user could readily compromise the server by using a form to send input to these scripting engines. This is a web-related vulnerability that could exist on any NT / Win 2000 system regardless of the web server software being used on the platform.
