3. Problem Description

a. VMware vCenter Update Manager Jetty Web server vulnerabilities
VMware vCenter Update Manager is an automated patch management solution for VMware ESX hosts and Microsoft virtual machines. Update Manager embeds the Jetty Web server which is a third party component.

The default version of the Jetty Web server in Update Manager is version 6.1.6 for which the following relevant vulnerabilities are reported.

A directory traversal vulnerability in Jetty allows for obtaining files from the system where Update Manager is installed by a remote, unauthenticated attacker. The attacker would need to be on the same network as the system where Update Manager is installed.

A cross-site scripting vulnerability in Jetty allows for running JavaScript in the browser of the user who clicks a URL containing a malicious request to Update Manager. For an attack to be successful the attacker would need to lure the user into clicking the malicious URL.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-1523 and CVE-2009-1524 to these issues.

VMware would like to thank Claudio Criscione of Secure Network for reporting these issues to us.

Column 4 of the following table lists the action required to remediate the vulnerabilities in each release, if a solution is available.

* Refer to VMware Knowledge Base article 1023962 for a workaround.
