FlatnuX NEXT CMS Cross-Site Request Forgery and Script Insertion Vulnerabilities


Description   Vulnerability Lab has discovered multiple vulnerabilities in FlatnuX NEXT CMS, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to conduct cross-site request forgery attacks.
1) Input passed via the "comment" parameter to index.php (when "mod" is set to "news" and "mode" is set to "comment") is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
2) Input passed via e.g. the "title_en", "summary_en", and "body_en" parameters to index.php (when "mod" is set to "news" and "mode" is set to "submitnews") is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
3) 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 e.g. add an administrator by tricking a logged in user into visiting a malicious web site.
The vulnerabilities are confirmed in version 2012-03.08. Other versions may also be affected.
