Lunar CMS is a freely distributable open source content management system written for use on servers running the ever so popular PHP5 & MySQL.
Lunar CMS suffers from a cross-site request forgery and a stored 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. Input passed to the 'subject' and 'email' POST parameters thru the 'Contact Form' extension/module 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.
