Windows SMB Elevation of Privilege Vulnerability

<p>An elevation of privilege vulnerability exists in the default Windows SMB Server configuration which allows anonymous users to remotely access certain named pipes that are also configured to allow anonymous access to users who are logged on locally. An unauthenticated attacker who successfully exploits this configuration error could remotely send specially crafted requests to certain services that accept requests via named pipes.</p> <p>To exploit the vulnerability, an attacker would have to be able to send SMB messages to an impacted Windows SMB Server for which the attacker does not already have valid credentials, and then identify an unpatched vulnerability in the handling of named pipe requests in one of the impacted services.</p> <p>The update addresses the vulnerability by correcting the Windows SMB Server default configuration.</p>
