Description

The BackWPup – WordPress Backup & Restore Plugin plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'backwpup_working' AJAX action in all versions up to, and including, 5.5.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve access to a back-up's filename while a backup is running. This information has little value on it's own, but could be used to aid in a brute force attack to retrieve back-up contents in limited environments (i.e. NGINX).

Attack-Flow Graph

Executive Summary

This vulnerability exists in the BackWPup WordPress plugin up to version 5.5.0, where a missing capability check on the 'backwpup_working' AJAX action allows authenticated users with Subscriber-level access or higher to access the filename of a backup while it is running. Although the filename alone has limited value, it could potentially be used to assist in brute force attacks to retrieve backup contents in certain environments.

Impact Analysis

The vulnerability could allow an attacker with low-level authenticated access to obtain backup filenames, which might be leveraged to perform brute force attacks to access backup contents. This could lead to unauthorized disclosure of sensitive data contained in backups, especially in environments like NGINX where such attacks might be feasible.
