Description

Windows servers with WebDAV enabled contain a flaw that may allow a remote attacker to execute arbitrary code. The issue is due to the ntdll.dll component of the WebDAV not properly sanitizing input to a path conversion function. If an attacker sends a specially crafted request to this function, they may be able to execute arbitrary code with SYSTEM privileges.
