Detailsinfo

A vulnerability has been found in rack up to 1.5.1 and classified as problematic. Affected by this vulnerability is the function Rack::File. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality. The summary by CVE is:

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."

The weakness was published 02/08/2013 by Ben Murphy (Website). It is possible to read the advisory at groups.google.com. This vulnerability is known as CVE-2013-0262 since 12/06/2012.
