I have access to an admin account on a IPB 2.1.3
I add php type of attachment files and upload a php shell on the site.. But when i want to launch it in my profile, it just download it.
So my question is how i can get the path to my php files like uploads/file.php (it doesnt work) and not juste get it with GET method in the url.
Any help for the upload dir or in general?

New extension .phtml
Mime type application/octet-stream .phtml

Upload your shell with ext shell.phtml and look in ./uploads/shell.phtml

Mime type : application/octet-stream .phtml or just application/octet-stream ?
Anyway, i dont find the file i upload... I saw that in ibp the location was crypted with something like MSG-id-dontremember-timestamp when the file was add. I am not sure, have you some clues?

Hmm when i upload the phtml file, i ve turn on the DEBUG mode, and when i get the location, i see it replace .phtml or .php by .ibp
Is there a way ipb doesnt change the extension?

If you upload "test.php.php", then you get "test.php.ibp"??

If so, then try to access "test.php.ibp" via web - there is big chance that php code will execute. It's old and widely known Apache behavior in case of unknown file extensions and "php." substring in filename Smile

I just test it, the location is always just *.ibp

Code:
INSERT INTO ibf_attachments (attach_ext,attach_file,attach_location,attach_thumb_location,attach_hits,attach_date,attach_temp,attach_pid,attach_post_key,attach_member_id,attach_filesize,attach_is_image) VALUES('php','test.php.php','post-2-1204950258.ipb','','',1204950258,0,'','6413df11172426d5798962a5cc0f85d0',2,83266,0)

As you can see - IPB is smart enough to rename file completely, so that ".php." trick will not work.

IPB is hard target, you can't find easy security holes from it Smile

AFAIR I managed to upload a shell on IPB 2.1.6 using "Emoticon Manager". Go to "Administration" ->"Look and feel"->"Manage emoticons" and upload your file into one of the directories e.g. default. Then you can acccess it from /forum/style_emoticons/default/shell.php
