"The MySQL Eventum install hosted on the remote web server is vulnerable
to a cross-site scripting attack because it fails to sanitize
user-supplied input to the 'email' parameter of the 'index.php' script
before using it to generate dynamic HTML output.

With a specially crafted URL, an attacker can use the remote server to
inject arbitrary HTML and script code into a user's browser to be
executed within the security context of the affected site.

Note that this install is also likely to be affected by several other
similar cross-site scripting vulnerabilities, although Nessus has not checked
for them.");
