remote Windows host is 5.1.x prior to 5.1.3 hotfix 1110787. It is,
therefore, affected by a reflected cross-site scripting (XSS)
vulnerability in the web user interface (UI), specifically within the
ePO computer management services, due to a failure to properly
validate user-supplied input to unspecified  parameters. An
authenticated, remote attacker can exploit this vulnerability, by
convincing a user into requesting a specially crafted URL, to execute
arbitrary script code in the user's browser session.");
