Russ McRee has reported some vulnerabilities in CompactCMS, which can be exploited by malicious people to conduct cross-site scripting and cross-site request forgery attacks.
1) Input passed to the "pagetitle", "subheader", and "urlpage" parameters to admin/index.php 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 pages by enticing a user to visit a malicious site.
The vulnerabilities are reported in version 1.1. Other versions may also be affected.
Solution: Update to version 1.2, which fixes some of the vulnerabilities.
