AI-suggested

To mitigate this vulnerability, European organizations should immediately update the BackWPup plugin to a version that includes the necessary authorization checks once available. Until a patch is released, organizations should restrict plugin access to only trusted administrators and disable user registration if not required. Implementing strict role-based access controls (RBAC) within WordPress to limit the number of users with editing or higher privileges can reduce the attack surface. Monitoring and auditing changes to site options and user roles can help detect suspicious activity early. Employing Web Application Firewalls (WAFs) with custom rules to block unauthorized attempts to invoke the save_site_option() function may provide temporary protection. Additionally, organizations should enforce strong authentication mechanisms and consider multi-factor authentication (MFA) for all users with elevated privileges. Regular backups and incident response plans should be reviewed and tested to ensure rapid recovery in case of compromise.

Description

The BackWPup – WordPress Backup & Restore Plugin plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the save_site_option() function in all versions up to, and including, 5.6.2. This makes it possible for authenticated attackers, with level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.
