Technical Details & Description:
Multiple persistent input validation web vulnerabilities has been discovered in the official BootCommerce CMS v3.2.1 cms web-application.
The vulnerability allows remote attackers to inject own malicious script codes with persistent attack vector to compromise browser to 
web-application requests from the application-side.

The vulnerabilities are located in the input fields of the billing address and shipping address module affecting check_out.php. Remote attackers 
can use the guest order option to inject own malicious persistent script code with the order process to provoke an execute of code in the frontend 
and backend to compromise. The order process allows unregistered users to order and checkout with artcle items were the contents are wrong sanitized.
After the order process the wrong validated content is delivered to the backend were an execute takes place on preview or interaction.

Successful exploitation of the vulnerability results in session hijacking, persistent phishing attacks, persistent external redirects to malicious 
source and persistent manipulation of affected application modules.
