Vulnerability from fkie_nvd - Published: 2025-05-07 05:15 - Updated: 2025-05-07 14:13
Severity ?
5.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N
Summary
The Login Lockdown & Protection plugin for WordPress is vulnerable to unauthorized nonce access due to a missing capability check on the ajax_run_tool function in all versions up to, and including, 2.11. This makes it possible for authenticated attackers, with Subscriber-level access and above, to obtain a valid nonce that can be used to generate a global unlock key, which can in turn be used to add arbitrary IP address to the plugin allowlist. This can only by exploited on new installations where the site administrator hasn't visited the loginlockdown page yet.

Esto permite a atacantes autenticados, con acceso de suscriptor o superior, obtener un nonce v\u00e1lido que puede usarse para generar una clave de desbloqueo global, la cual, a su vez, puede usarse para a\u00f1adir una direcci\u00f3n IP arbitraria a la lista de permitidos del complemento. Esto solo se puede explotar en nuevas instalaciones donde el administrador del sitio a\u00fan no haya visitado la p\u00e1gina de loginlockdown."
