The application allows users to perform certain actions via HTTP requests without performing proper checks to verify the requests validity. An authenticated user's browser can be forced to generate and disclose the WordPress database and code backups via the vulnerable backup function by tricking the user into visiting a malicious web site. ----------------------------------------------------------------------------------------------- Proof of Concept The proof of concept HTML page, if visited by a logged-in administrative user, raises two requests (`/wp-admin/admin.php?page=duplicator&tab=new2` and `/wp-admin/admin-ajax.php?action=duplicator_package_build`) forcing the creation of the WordPress source code, database, and install scripts backup in the paths `/wp-snapshots/ratiosec_ratiosec_archive.zip`, `/wp-snapshots/ratiosec_ratiosec_database.sql`, and `/wp-snapshots/ratiosec_ratiosec_installer.php`. Once generated, the backup archives can be downloaded by the attacker with no authentication. See the proof of concept code on the RatioSec Research website. http://www.ratiosec.com/2016/duplicator-wordpress-plugin-source-database-disclosure-via-csrf/ ----------------------------------------------------------------------------------------------- Solution Update to version 1.1.4. ----------------------------------------------------------------------------------------------- Timeline - First contact: 29th January, 2016 - Disclosure: 29th January, 2016. Preliminary date set to 19th, February 2016. - Postponed: Date pushed back to 19th February, 2016 - Fixed in GIT: 6th February, 2016 - Fixed Release: 9th February, 2016 - Advisory Publication: 9th February, 2016 ----------------------------------------------------------------------------------------------- Advisory URL http://www.ratiosec.com/2016/duplicator-wordpress-plugin-source-database-disclosure-via-csrf/ RatioSec Research Mail: research at ratiosec dot com Web: http://www.ratiosec.com/ Twitter: https://twitter.com/ratio_sec
