Descriptions

Butor Portal before 1.0.27 is affected by a Path Traversal vulnerability leading to a pre-authentication arbitrary file download. Effectively, a remote anonymous user can download any file on servers running Butor Portal. WhiteLabelingServlet is responsible for this vulnerability. It does not properly sanitize user input on the theme t parameter before reusing it in a path. This path is then used without validation to fetch a file and return its raw content to the user via the /wl?t=../../...&h= substring followed by a filename.

Butor Portal versiones anteriores a 1.0.27, está afectado por una vulnerabilidad de Salto de Ruta conllevando a una descarga de archivos arbitrarios previa a la autenticación. Efectivamente, un usuario anónimo remoto puede descargar cualquier archivo en servidores ejecutando Butor Portal. La función WhiteLabelingServlet es responsable de esta vulnerabilidad. No sanea apropiadamente la entrada del usuario en el parámetro t del tema antes de reutilizarlo en una ruta. Esta ruta luego es usada sin comprobación para recuperar un archivo y devolver su contenido crudo para el usuario por medio de la subcadena /wl?t=../../...&h= seguida por un nombre de archivo.
