An issue was discovered in Total.js CMS 12.0.0. An authenticated user with the Pages privilege can conduct a path traversal attack (../) to include .html files that are outside the permitted directory. Also, if a page contains a template directive, then the directive will be server side processed. Thus, if a user can control the content of a .html file, then they can inject a payload with a malicious template directive to gain Remote Command Execution. The exploit will work only with the .html extension.

An issue was discovered in Total.js CMS 12.0.0. An authenticated user with limited privileges can get access to a resource that they do not own by calling the associated API. The product correctly manages privileges only for the front-end resource path, not for API requests. This leads to vertical and horizontal privilege escalation.

Total.js CMS 12.0.0 has XSS related to themes/admin/views/index.html (item.message) and themes/admin/public/ui.js (column.format).
