Vulnerabilidades do Kraftplugins Demo Importer Plus

The Demo Importer Plus plugin for WordPress is vulnerable to XML External Entity Injection (XXE) in all versions up to, and including, 2.0.9 via the SVG file upload functionality. This makes it possible for authenticated attackers, with Author-level access and above, to achieve code execution in vulnerable configurations. This only impacts sites on versions of PHP older than 8.0.

The Demo Importer Plus plugin for WordPress is vulnerable to unauthorized modification of data, loss of data, and privilege escalation due to a missing capability check on the Ajax::handle_request() function in all versions up to, and including, 2.0.8. This makes it possible for authenticated attackers, with Subscriber-level access and above, to trigger a full site reset, dropping all database tables except users/usermeta and re-running wp_install(), which also assigns the Administrator role to the attacking subscriber account.

The Demo Importer Plus plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 2.0.6. This is due to insufficient file type validation detecting WXR files, allowing double extension files to bypass sanitization while being accepted as a valid WXR file. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
