| Description | The Import and export users and customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.5.11 This is due to a non-atomic multi-option write sequence in the `ACUI_Cron::save_settings()` function, which persists `acui_cron_activated`, `acui_cron_configured_by`, `acui_cron_user_id`, and `acui_cron_path_to_file` before reaching the authorization gate that calls `wp_die()` when a non-promoter submits a role. This makes it possible for authenticated attackers holding a custom delegated role with `create_users` but without `promote_users` or `edit_users` to escalate their privileges to Administrator, provided a prior administrator cron-tab save exists and no successful save intervenes before the next unattended cron tick processes the attacker's repointed CSV file. |
