Overview

Microsoft FrontPage Server Extensions contains a vulnerability that allows remote attackers to execute arbitrary code with local system privileges.

The FPSE contains a buffer overflow vulnerability in its support of remote debugging. This vulnerability can be exploited by an unauthenticated remote attacker and allows arbitrary code to be executed with local system privileges.

Impact

This vulnerability allows unauthenticated remote attackers to execute arbitrary code with local system privileges.

Disable FrontPage Server Extensions

As a an interim measure, sites may reduce their exposure to this vulnerability by disabling FrontPage Server Extensions. Note that this may reduce the functionality of sites that utilize FPSE extensions.

Disable Internet Information Server

The IIS web server is installed by default on several versions of Microsoft Windows. As a general rule, the CERT/CC recommends that system administrators disable or remove any nonessential software. In this case, IIS should be removed from any host that is not expected to serve web pages.
