Detailsinfo

A vulnerability, which was classified as critical, was found in Ruby on Rails up to 3.2.22.1/4.1.14.1 (Programming Language Software). This affects an unknown functionality of the component Action View. 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, and integrity. The summary by CVE is:

Directory traversal vulnerability in Action View in Ruby on Rails before 3.2.22.2 and 4.x before 4.1.14.2 allows remote attackers to read arbitrary files by leveraging an application's unrestricted use of the render method and providing a .. (dot dot) in a pathname. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-0752.

The weakness was published 04/07/2016 (Website). The advisory is shared at lists.opensuse.org. This vulnerability is uniquely identified as CVE-2016-2097 since 01/29/2016.
