"The version of Gallery hosted on the remote web server is affected by a
cross-site scripting vulnerability because it fails to properly sanitize
user-supplied input to the 'username' parameter of the 'login.php'
script.  An attacker could exploit this flaw 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 the application is reportedly affected by multiple additional
cross-site scripting vulnerabilities as well as an information
disclosure vulnerability, although Nessus has not tested for these.");
