An issue was discovered in Navigate CMS 2.8 and 2.9 r1433. The query parameter fid on the resource navigate.php does not perform sufficient data validation and/or encoding, making it vulnerable to reflected XSS.
An issue was discovered in Navigate CMS 2.9 r1433. When performing a password reset, a user is emailed an activation code that allows them to reset their password. There is, however, a flaw when no activation code is supplied. The system will allow an unauthorized user to continue setting a password, even though no activation code was supplied, setting the password for the most recently created user in the system (the user with the highest user id).
The install_from_hash functionality in Navigate CMS 2.9 does not consider the .phtml extension when examining files within a ZIP archive that may contain PHP code, in check_upload in lib/packages/extensions/extension.class.php and lib/packages/themes/theme.class.php.
An issue was discovered in Navigate CMS through 2.8.7. It allows Directory Traversal because lib/packages/templates/template.class.php mishandles ../ and ..\ substrings.
