      "value": "Kirby is an open-source content management system. A vulnerability in versions prior to 3.9.8.3, 3.10.1.2, and 4.7.1 affects all Kirby sites that use the `snippet()` helper or `$kirby-\u003esnippet()` method with a dynamic snippet name (such as a snippet name that depends on request or user data). Sites that only use fixed calls to the `snippet()` helper/`$kirby-\u003esnippet()` method (i.e. calls with a simple string for the snippet name) are *not* affected. A missing path traversal check allowed attackers to navigate and access all files on the server that were accessible to the PHP process, including files outside of the snippets root or even outside of the Kirby installation. PHP code within such files was executed. Such attacks first require an attack vector in the site code that is caused by dynamic snippet names, such as `snippet(\u0027tags-\u0027 . get(\u0027tags\u0027))`. It generally also requires knowledge of the site structure and the server\u0027s file system by the attacker, although it can be possible to find vulnerable setups through automated methods such as fuzzing. In a vulnerable setup, this could cause damage to the confidentiality and integrity of the server. The problem has been patched in Kirby 3.9.8.3, Kirby 3.10.1.2, and Kirby 4.7.1. In all of the mentioned releases, Kirby maintainers have added a check for the snippet path that ensures that the resulting path is contained within the configured snippets root. Snippet paths that point outside of the snippets root will not be loaded."

      "value": "Kirby es un sistema de gesti\u00f3n de contenido de c\u00f3digo abierto. Una vulnerabilidad en versiones anteriores a 3.9.8.3, 3.10.1.2 y 4.7.1 afecta a todos los sitios de Kirby que usan el asistente `snippet()` o el m\u00e9todo `$kirby-\u0026gt;snippet()` con un nombre de fragmento din\u00e1mico (por ejemplo, un nombre de fragmento que depende de la solicitud o de los datos del usuario). Los sitios que solo usan llamadas fijas al asistente `snippet()` o al m\u00e9todo `$kirby-\u0026gt;snippet()` (es decir, llamadas con una cadena simple para el nombre del fragmento) *no* se ven afectados. La falta de una comprobaci\u00f3n de path traversal permiti\u00f3 a los atacantes navegar y acceder a todos los archivos del servidor accesibles para el proceso PHP, incluyendo archivos fuera del root de los fragmentos o incluso fuera de la instalaci\u00f3n de Kirby. Se ejecut\u00f3 el c\u00f3digo PHP dentro de dichos archivos. Tales ataques primero requieren un vector de ataque en el c\u00f3digo del sitio que es causado por nombres de fragmentos din\u00e1micos, como `snippet(\u0027tags-\u0027 . get(\u0027tags\u0027))`. Generalmente tambi\u00e9n requiere conocimiento de la estructura del sitio y el sistema de archivos del servidor por parte del atacante, aunque puede ser posible encontrar configuraciones vulnerables a trav\u00e9s de m\u00e9todos automatizados como fuzzing. En una configuraci\u00f3n vulnerable, esto podr\u00eda causar da\u00f1os a la confidencialidad e integridad del servidor. El problema ha sido parcheado en Kirby 3.9.8.3, Kirby 3.10.1.2 y Kirby 4.7.1. En todas las versiones mencionadas, los mantenedores de Kirby han agregado una comprobaci\u00f3n para la ruta del fragmento que garantiza que la ruta resultante est\u00e9 contenida dentro del root de fragmentos configurada. Las rutas de fragmentos que apuntan fuera del root de fragmentos no se cargar\u00e1n."
