Descriptions

CodeIgniter is a PHP full-stack web framework. When an application uses (1) multiple session cookies (e.g., one for user pages and one for admin pages) and (2) a session handler is set to `DatabaseHandler`, `MemcachedHandler`, or `RedisHandler`, then if an attacker gets one session cookie (e.g., one for user pages), they may be able to access pages that require another session cookie (e.g., for admin pages). This issue has been patched, please upgrade to version 4.2.11 or later. As a workaround, use only one session cookie.

CodeIgniter es un framework web PHP full-stack. Cuando una aplicación utiliza (1) múltiples cookies de sesión (por ejemplo, una para páginas de usuario y otra para páginas de administración) y (2) un controlador de sesión está configurado en `DatabaseHandler`, `MemcachedHandler` o `RedisHandler`, entonces, si un atacante obtiene una cookie de sesión (por ejemplo, una para páginas de usuario), es posible que pueda acceder a páginas que requieren otra cookie de sesión (por ejemplo, para páginas de administración). Este problema ha sido solucionado; actualice a la versión 4.2.11 o posterior. Como solución alternativa, utilice solo una cookie de sesión.
