"The version of Atmail WebMail running on the remote host is vulnerable
to multiple cross-site scripting issues. 'webadmin/admin.php' fails to
sanitize input to the 'func' parameter, and to the 'type' parameter
(when 'func' is set to 'stats'). This is known to affect version 5.6.1
(5.61) and may affect previous versions as well.

A remote attacker could exploit this by tricking a user into
requesting a web page with arbitrary script code injected. This could
lead to consequences such as stolen authentication credentials.");
