The remote VMware ESX host is missing a security-related patch. It is, therefore, affected by multiple cross-site scripting (XSS) vulnerabilities in WebWorks Help due to improper sanitization of user-supplied input to unspecified parameters or to messages used in topic links. A remote attacker can exploit these to inject arbitrary script code or HTML into the user’s browser session.
