Horde < 3.3.3 / 3.2.4 Horde_Image::factory driver Argument Local File Inclusion

High

Synopsis

The remote web server contains a PHP application that is susceptible to a local file inclusion attack.

Description

The version of Horde, Horde Groupware, or Horde Groupware Webmail Edition installed on the remote host fails to filter input to the 'driver' argument of the 'Horde_Image: : factory' method before using it to include PHP code in 'lib/Horde/Image.php'. Regardless of PHP's 'register_globals' and 'magic_quotes_gpc' settings, an unauthenticated attacker can exploit this issue to view arbitrary files or possibly to execute arbitrary PHP code on the remote host, subject to the privileges of the web server user ID.

Note that this install is also likely affected by a cross-site scripting issue in the 'services/portal/cloud_search.php' script.

Solution

Upgrade to version 3.3.3 / 3.2.4 or higher.
