Overview
Cutenews 1.3 information disclosure
Discovered on 2003, July, 12th
Vendor: CutePHP
Cutenews is a powerful and easy for using
news management system that use flat files to store its database. It supports comments and
archives, search function, image uploading, backup function, IP banning, flood protection ...
Mainely, the first job a hacker does, is to retreive a maximum of information from the target server.
Cutenews can help much in this task.
For more information, I suggest to read phpinfo() et la sécurité by frog-m@n (french document).

Details
In the file index.php, a condition can be made to execute the PHP function phpinfo();
Here is the interesting lines :
if($HTTP_SERVER_VARS['QUERY_STRING'] == "debug"){ debug(); }
...
function debug(){
global $config_version_name, $config_version_id, $config_http_script_dir;
echo"<center><b>CuteNews Debug Information:</b><hr><br>";
echo"Script Version/ID: $config_version_name / $config_version_id<br>";
echo"\$config_http_script_dir: $config_http_script_dir<br><BR>";
echo"<hr>";
phpinfo();
exit();
}
Exploit
The exploit is really easy : Give the debug argument to the index.php :
http://victim.com/cutenews/index.php?debug
You will get the classical phpinfo page :
Solution
We suggest to delete the following line from your index.php file :
if($HTTP_SERVER_VARS['QUERY_STRING'] == "debug"){ debug(); }
The vendor has been informed.
