Re: dotproject <= 2.0.1 remote code execution

I'm not sure I understand why this is a problem. As you have stated register_globals must be set to on before any of this can be triggered. In terms on register_globals being on by default, that hasn't been the case in PHP for quite some time.
Also, I am intrigued by the claim that 'protection.php' is vulnerable. There is no 'protection.php' anywhere in the dotProject tree.
As pointed out to you privately, the simple solution is to turn register_globals off.

dotproject <= 2.0.1 remote code execution
======================================

        Software: dotProject <= 2.0.1
        Severity: Arbitrary code execution, Path/Information Disclosure
        Risk: High

        Description:
         dotProject is a volunteer supported Project Management application.

        Details:
         The 'protection.php' script does not properly validate user-supplied 
input in the 'siteurl' parameter.
         Some user-supplied input is not checked correctly so an attacker can 
include a remote php file and
         execute arbitrary phpcode or arbitrary system command via eval().

         Because there are over 10 Bugs I only post the vulnerable files + 
parameters which are not checked.
         To exploit these vulnerables register_globals have to be set ON 
(default).

         1) /includes/db_adodb.php?baseDir=[REMOTE INCLUDE]
2) /includes/db_connect.php?baseDir=[REMOTE INCLUDE] 3) /includes/session.php?baseDir=[REMOTE INCLUDE] 4) /modules/projects/gantt.php?dPconfig[root_dir]=[REMOTE INCLUDE] 5) /modules/projects/gantt2.php?dPconfig[root_dir]=[REMOTE INCLUDE] 6) /modules/projects/vw_files.php?dPconfig[root_dir]=[REMOTE INCLUDE] 7) /modules/admin/vw_usr_roles.php?baseDir=[REMOTE INCLUDE] 8) /modules/public/calendar.php?baseDir=[REMOTE INCLUDE] 9) /modules/public/date_format.php?baseDir=[REMOTE INCLUDE] 10) /modules/tasks/gantt.php?baseDir=[REMOTE INCLUDE] 

         There are also some path discolsure bugs:

         Nearly ALL files in /db/ give out some nice php-errors by accessing 
them directly with the parameter
         baseDir=foobar.

         Then, if the /doc/ directory is not deleted (default) you can access 
to two varoius files which
         disclose you some system informations:

         1) /docs/phpinfo.php - A phpinfo() file.
2) /docs/check.php - Some more informations about the installed dotProject. 

        Solution:
         Turn register_globals OFF, delete the /docs/ dir and cover /db/ dir 
with an htaccess.
