Introduction:
=============
FBC-Market is a application that allows you to run your own online marketplace
or classifieds listing site
similar to Craigslist. It was written in PHP and uses MySQL to for data
storage. Additionally, it uses
jQuery for elegant effects and that web 2.0 pizzazz you ve always dreamed of.
The general design is simple and clean which should go well with any site,
customization can be done easily
through the CSS file. You can add your header and footer to it or include it in
an iframe and you are ready
to roll. And if you want to get your hands dirty in code, the comments will
help you know what is going on.

Severity:
=========
Medium(+)
Details:
========
1.1
Multiple input validation vulnerabilities(persistent) are detected on
FreeBoxClubs FBC-Market CMS v1.1 web application.
Attackers can include persistent malicious script codes to manipulate specific
customer requests & modules.
The vulnerability allows an attacker also to hijack customer/admin sessions via
persistent script code inject.
The vulnerabilities are located on the category add module of the application.

1.2
An client-side input validation vulnerability(non-persistent) is detected on
FreeBoxClubs FBC-Market CMS v1.1 web application.
Remote attackers can hijack customer/admin accounts via malicious link on
client side with medium required user inter action.
Vulnerable Module(s):
[+] Login

Proof of Concept:
=================
The vulnerabilities can be exploited by local low privileged user accounts or
remote attackers with medium
required user inter action or local low privileged user accounts. For
demonstration or reproduce ...

Risk:
=====
The security risk of the persistent input validation vulnerabilities are
estimated as medium(+).
The security risk of the client-side login xss (cross site Scripting)
vulnerability is estimated as low(+).
