# Description about Software :
***************************

This Joomla Survey Extension will allow you to create professional looking surveys in

your own Joomla environment. Unlike some online survey solutions, with

BF Survey you retain full control over your data, and can customise

to suit whatever your needs are. It can be as simple as creating a survey

category, adding quesitons, then add your menu item. Or if you have more

complex needs, you can use this software to do some really fancy stuff

such as showing or hiding questions based on previous question responses.

# Impact :
***********

Joomla BF Survey Pro 2.13.1 component for Joomla is prone to an SQL-injection

vulnerability because it fails to sufficiently sanitize user-supplied

data before using it in an SQL query.

Exploiting this issue could allow an attacker to compromise the application,

access or modify data, or exploit latent vulnerabilities in the underlying database.

A remote attacker can send a specially crafted request to the vulnerable application

and execute arbitrary SQL commands in application`s database.

This vulnerability could potentially allow remote attackers to execute arbitrary

SQL commands, and manipulate database contents to gain administration

access to the vulnerable application.

Further exploitation of this vulnerability may result in unauthorized data manipulation.

An attacker can exploit this issue using a browser.
