------------SA-2007-022 - BOOST - FILE OVERWRITE------------

* Advisory ID: DRUPAL-SA-2007-022.

* Project: Boost (third-party module)

* Version: 4.7.x-1.*, 5.x-0.*

* Date: 2007-10-03

* Security risk: Critical

* Exploitable from: Remote

* Vulnerability: Filesystem overwrite

------------DESCRIPTION------------

The Boost [ http://drupal.org//project/boost ] module provides a static
file-based cache of Drupal pages for anonymous users. A vulnerability allows an
attacker to create or overwrite any filename in any directory that the web
server can write to. The affected file will always contain the fully rendered
HTML for a single Drupal page; the attacker cannot control the content of the
affected file in any other way.

As an example, since most Drupal web servers have write access to the Drupal
installation directory, the attacker could replace Drupal's index.php with the
HTML of another page from the same site of his choosing, causing /every/ page
from the attacked site to appear like the chosen page.

------------VERSIONS AFFECTED------------

* 5.x:

* Boost before version 5.x-1.0

* 4.7.x:

* Boost before version 4.7.x-1.0

Drupal core is not affected. If you do not use the contributed Boost module,
there is nothing you need to do.

------------SOLUTION------------

Install the latest version:

* 5.x:

* Boost 5.x-1.0 [ http://drupal.org//node/179811 ]

* 4.7.x:

* Boost 4.7.x-1.0 [ http://drupal.org//node/179810 ]
