In Kirby CMS (getkirby/cms) before version 3.4.5, and Kirby Panel before version 2.5.14 , an editor with full access to the Kirby Panel can upload a PHP .phar file and execute it on the server. This vulnerability is critical if you might have potential attackers in your group of authenticated Panel users, as they can gain access to the server with such a Phar file. Visitors without Panel access *cannot* use this attack vector. The problem has been patched in Kirby 2.5.14 and Kirby 3.4.5. Please update to one of these or a later version to fix the vulnerability. Note: Kirby 2 reaches end of life on December 31, 2020. We therefore recommend to upgrade your Kirby 2 sites to Kirby 3. If you cannot upgrade, we still recommend to update to Kirby 2.5.14."}, {"lang": "es", "value": "Kirby es un CMS. En Kirby CMS (getkirby/cms) anterior a la versi\u00f3n 3.4.5 y Kirby Panel anterior a la versi\u00f3n 2.5.14, un editor con acceso completo a Kirby Panel puede cargar un archivo PHP .phar y ejecutarlo en el servidor. Esta vulnerabilidad es cr\u00edtica si puede tener atacantes potenciales en su grupo de usuarios autenticados de Panel, ya que pueden conseguir acceso al servidor con dicho archivo Phar. Los visitantes sin acceso a Panel *cannot* usar este vector de ataque. El problema ha sido parcheado en Kirby versi\u00f3n 2.5.14 y Kirby versi\u00f3n 3.4.5. Actualice a uno de estas o una versi\u00f3n posterior para corregir la vulnerabilidad. Nota: Kirby versi\u00f3n 2 llega al final de su vida \u00fatil el 31 de diciembre de 2020.
