Descriptions

Missing Authorization vulnerability in POSIMYTH Nexter.This issue affects Nexter: from n/a through 2.0.3.

Vulnerabilidad de autorización faltante en POSIMYTH Nexter. Este problema afecta a Nexter: desde n/a hasta 2.0.3.

The Nexter theme for WordPress is vulnerable to unauthorized modification of data due to missing capability checks on several functions such as nexter_extra_ext_active_ajax, nexter_extra_ext_deactivate_ajax, nexter_ext_wp_replace_url_settings_ajax, nexter_ext_wp_duplicate_post_settings_ajax, nexter_ext_save_data_ajax, and more in versions up to, and including, 2.0.3. This makes it possible for authenticated attackers, with subscriber-level access and above, to duplicate posts, modify settings, and more.
