Summary

Masa CMS is a content management system forked from Mura CMS. In versions 7.5.2 and earlier, the createBundle method in `csettings.cfc` does not properly validate anti-CSRF tokens for site bundle creation requests. An attacker can craft a malicious webpage or link that, when visited by a logged-in administrator, triggers the silent creation of a comprehensive site bundle. This bundle is saved to a predictable, publicly accessible web directory. An unauthenticated attacker can then retrieve the bundle and obtain site content, user account data, password hashes, form submissions, email lists, plugins, and configuration data. This issue has been fixed in versions 7.2.10, 7.3.15, 7.4.10, and 7.5.3. As a workaround, remove unexpected bundle files from public directories, restrict access to the affected endpoint, and limit exposure of administrative sessions.
