I ve already coded what I need to get the administrator's cookies. But before retrieving the admin's cookie, my question is: once I have got the cookie, how do I access the administration panel(*)? And from there what are the things I can do to install a web shell(**)? the forum should be phpBB 2.0.20 (according to /docs/CHANGELOG.html) (*) I know I have to perform a session hijack, but since then, is the admin panel accessible or I have to input the password anyways? (**) I ve already used a RCE script (by rgod) but idk if I was able to extract the admin session's id from the cookie (prolly not), where should I look to find the admin session id? does that session id grant me access to the admin panel? Please I don't wanna beg anyone, but I m tired of searching google and finding nothing.

So if you have stolen sessionID, then you can't use it in most cases. Now, there is something else you can try. If you can trick admin to visit your website and in same time he's logged in as admin and if you can use XSS hole (classical reflected XSS scenario), then you can actually commit CSRF attack!! Phpbb uses cryptographic nonce as anti-XSRF measure, but XSS will make it useless!! So for example you can make victim's browser to submit new admin creation form - silently and with user data you can provide:) http://en.wikipedia.org/wiki/XSRF Posted: Thu Nov 06, 2008 2:12 pm theanderson Regular user Joined: Nov 03, 2008 Posts: 6 waraxe wrote: As far as i know, phpbb is checking IP address/session ID match.

(googling in the while...) EDIT: Found something at http://hackish.altervista.org/forum/viewtopic.php?t=405 Code: <html> <iframe name="hackinginside" frameborder="0" height="0" width="0"></iframe> <form action="http://site.com/path/groupcp.php?g=[GROUP_ID]" method="post" name="vincy" target="hackinginside"> <input type="hidden" name="username" value="[YOUR_NAME]"> <input type="submit" name="add" value="Add Member"></form> <script>document.vincy.submit()</script> </html> But I don't know how much could this help me, because the forum's admin doesn't seem to belong to any "group"...
