CVE reference:CVE-2008-4898
CVE-2008-4899


Description:
Russ McRee has reported some vulnerabilities in RateMe, which can be exploited by malicious people to conduct cross-site request forgery and cross-site scripting attacks.

1) Input passed to the "rate" parameter when submitting a rating is not properly sanitised 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.

2) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the request. This can be exploited to e.g. delete arbitrary comments when a logged-in user visits a malicious site.

The vulnerabilities are reported in version 1.3.3. Other versions may also be affected.

Solution:
Edit the source code to ensure that input is properly sanitised. Do not browse untrusted sites while being logged-in to the application.
