CVE-2013-0262: Path Traversal
First published: Fri Feb 08 2013(Updated: )
`rack/file.rb` (`Rack::File`) in Rack 1.5.x before 1.5.2 and 1.4.x before 1.4.5 allows attackers to access arbitrary files outside the intended root directory via a crafted `PATH_INFO` environment variable, probably a directory traversal vulnerability that is remotely exploitable, aka "symlink path traversals."
