The version of the Horde application framework hosted on the remote web server fails to sanitize user input to the ‘subdir’ parameter of the ‘util/icon_browser.php’ script before using it to generate dynamic HTML output.

An attacker may be able to leverage this issue to inject arbitrary HTML or script code into a user’s browser to be executed within the security context of the affected site.
