Technical Details & Description:  
A persistent input validation web vulnerability has been discovered in  
the official Sellacious eCommerce Shop CMS (2020 Q1).  
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 cross site web vulnerabilities are located in the all the adress  
input fields of the `Manage Your Addresses` module.  
Remote attackers are able to register a low privilege user account to  
inject own malicious script code to the adress  
information page. The execution of the script code occurs each time the  
adress information is used in the web ui of  
the ecommerce application. The request method to inject is POST and the  
attack vector is persistent on the application-side.  
Successful exploitation of the vulnerabilities results in session  
hijacking, persistent phishing attacks, persistent  
external redirects to malicious source and persistent manipulation of  
affected application modules.
