Summary
Craft CMS stores arbitrary content provided by unauthenticated users in session files. This content could be accessed and executed, possibly using an independent vulnerability. Craft CMS redirects requests that require authentication to the login page and generates a session file on the server at '/var/lib/php/sessions'. Such session files are named 'sess_[session_value]', where '[session_value]' is provided to the client in a 'Set-Cookie' response header. Craft CMS stores the return URL requested by the client without sanitizing parameters. Consequently, an unauthenticated client can introduce arbitrary values, such as PHP code, to a known local file location on the server. Craft CMS versions 5.7.5 and 4.15.3 have been released to address this issue.

Este contenido podr\u00eda ser accedido y ejecutado, posiblemente aprovechando una vulnerabilidad independiente. Craft CMS redirige las solicitudes que requieren autenticaci\u00f3n a la p\u00e1gina de inicio de sesi\u00f3n y genera un archivo de sesi\u00f3n en el servidor, en `/var/lib/php/sessions`. Estos archivos de sesi\u00f3n se denominan `sess_[session_value]`, donde `[session_value]` se proporciona al cliente en un encabezado de respuesta `Set-Cookie`. Craft CMS almacena la URL de retorno solicitada por el cliente sin par\u00e1metros de limpieza. Por lo tanto, un cliente no autenticado puede introducir valores arbitrarios, como c\u00f3digo PHP, en una ubicaci\u00f3n de archivo local conocida en el servidor. Se han publicado las versiones 5.7.5 y 4.15.3 de Craft CMS para solucionar este problema."
