Horde contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'url' variable upon submission to the test.php script when the 'mode' variable is set to the value 'phpinfo' or 'filetest'. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.

Debian users should upgrade to the version recommended by the distribution as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds. For other users currently there are no known upgrades, patches, or workarounds available to correct this issue.
