Some vulnerabilities have been discovered in CMS Made Simple, which can be exploited by malicious people to conduct cross-site request forgery attacks and disclose sensitive information.
1) The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to e.g. change group permissions or change the administrative password by tricking a logged in administrative user into visiting a malicious web site.
2) Input passed via the "default_cms_lang" parameter to various scripts e.g. admin/addbookmark.php, admin/addcontent.php, or admin/adminlog.php is not properly verified before being used to include files in lib/translation.functions.php. This can be exploited to include arbitrary files from local resources via directory traversal sequences and URL-encoded NULL bytes.
The vulnerabilities are confirmed in version 1.8. Other versions may also be affected.
Solution: Update to version 1.10.1.
