Hi, I think there is still a major vulnerability exists in the latest Rails 1.1.5.
The problem is in the routing.rb file and safe_load_paths method. Because of the erroneous regexp it is possible to perform a DOS attack on any rails application. To reproduce: 1. start your application 2. use this url: http://localhost:3000/debug Routing module will load standard debug.rb script which stops a dispatcher process waiting for a terminal input. Actually this way it is possible to load any script from the ruby standard library.
