Descriptions

The WEBrick gem 1.4.2 for Ruby allows directory traversal if the attacker once had local access to create a symlink to a location outside of the web root directory. NOTE: The vendor states that this is analogous to Options FollowSymlinks in the Apache HTTP Server, and therefore it is "not a problem.

** EN DISPUTA ** La WEBrick gem versión 1.4.2 para Ruby permite salto de directorio si el atacante alguna vez tuvo acceso local para crear un enlace simbólico a una ubicación fuera del directorio web root. NOTA: El proveedor declara que esto es similar a las Opciones FollowSymlinks en el Servidor HTTP de Apache, y por lo tanto "no es un problema".
