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.
Request Method(s):
[+] POST
Vulnerable Module(s):
[+] Manage Details
Vulnerable Parameter(s):
[+] name
[+] phone
[+] address
Affected Module(s):
[+] manage profile
[+] products branding
Proof of Concept (PoC):
=======================
The html injection web vulnerabilities can be exploited by remote attackers
with privileged accountant access and with low user interaction.
For security demonstration or to reproduce the persistent cross site web
vulnerability follow the provided information and steps below to continue.
