RealtyScript v4.0.2 Multiple CSRF And Persistent XSS Vulnerabilities

Vendor: Next Click Ventures

Product web page: http://www.realtyscript.com

Affected version: 4.0.2

Summary: RealtyScript is award-winning real estate software that makes

it effortless for a real estate agent, office, or entrepreneur to be

up and running with a real estate web site in minutes. The software

is in daily use on thousands of domain names in over 40 countries and

has been translated into over 25 languages.

Desc: The application allows users to perform certain actions via HTTP

requests without performing any validity checks to verify the requests.

This can be exploited to perform certain actions with administrative

privileges if a logged-in user visits a malicious web site. Multiple

cross-site scripting vulnerabilities were also discovered. The issue

is triggered when input passed via the multiple parameters is not

properly sanitized before being returned to the user. This can be

exploited to execute arbitrary HTML and script code in a user's browser

session in context of an affected site.

Tested on: Apache/2.4.6 (CentOS)

PHP/5.4.16

MariaDB-5.5.41
