The HTTP TRACK method returns the contents of client HTTP requests in the entity-body of the TRACK response. This behavior could be leveraged by attackers to access sensitive information, such as cookies or authentication data, contained in the HTTP headers of the request. Attackers may abuse HTTP TRACK functionality to gain access to information in HTTP headers that is not otherwise available via the DOM interface. Examples of such information are cookies and authentication data. In the presence of other cross-site domain vulnerabilities in web browsers, sensitive header information could be read from domains other than the target of the HTTP TRACK request.

Based on your site requirements and policy, you should consider disabling HTTP TRACK support in your web server. For Apache web servers, use the Apache mod_rewrite module to deny HTTP TRACK requests or to permit only the methods needed to meet site requirements and policy. For Microsoft's Internet Information Service (IIS), download the URLScan tool from Microsoft to deny HTTP TRACK requests or to permit only the methods needed to meet site requirements and policy. Upgrade to the latest version of Microsoft IIS (6.0 or later), available from the Microsoft Web site. For other web servers, consult your documentation for details.
