Technical Details & Description:  
================================  
Multiple html injection web vulnerabilities has been discovered in the official Active Super Shop Multi-vendor CMS v2.5 web-application.  
The web vulnerability allows remote attackers to inject own html codes with persistent vector to manipulate application content.  
  
The persistent html injection web vulnerabilities are located in the name, phone and address parameters of the manage profile and products branding module.  
Remote attackers with privileged accountant access are able to inject own malicious script code in the name parameter to provoke a persistent execution on  
profile view or products preview listing. There are 3 different privileges that are allowed to access the backend like the accountant (low privileges), the  
manager (medium privileges) or the admin (high privileges). Accountants are able to attack the higher privileged access roles of admins and manager on preview  
of the elements in the backend to compromise the application. The request method to inject is post and the attack vector is persistent located 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.

Proof of Concept (PoC):  
=======================  
The html injection web vulnerabilities can be exploited by remote attackers with privileged accountant access and with low user interaction.
