===========http://www.majorsecurity.de/index_2.php?major_rls=major_rls33 

Introduction
===========ShopSystems is a web shop system.

More Details
===========SQL injection:
Input passed directly to the "sessid" parameter in "index.php" is not properly sanitised before being used in a SQL query.
This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Fix
==none known

Solution
============Edit the source code to ensure that input is properly sanitised.
You should work with the "intval()" and "mysql_real_escape_string()" or "addslashes()" php-function to ensure that sql statements
can't be delivered over the "get" variables. 

Example:
$pass = htmlentities($_POST['pass']);
$test = htmlspecialchars($_GET('test'));
$id = intval($_POST['id']);
?>
