Detailsinfo

A vulnerability, which was classified as problematic, was found in Ruby on Rails (Programming Language Software). Affected is some unknown functionality in the library actionpack/lib/action_dispatch/middleware/static.rb of the component Assets. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality. CVE summarizes:

Directory traversal vulnerability in actionpack/lib/action_dispatch/middleware/static.rb in Action Pack in Ruby on Rails 3.x before 3.2.20, 4.0.x before 4.0.11, 4.1.x before 4.1.7, and 4.2.x before 4.2.0.beta3, when serve_static_assets is enabled, allows remote attackers to determine the existence of files outside the application root via a /..%2F sequence.
