A vulnerability, which was classified as problematic, has been found in WEBrick 1.8/1.8 P114/1.8 P115/1.9/1.9 1. Affected by this issue is some unknown functionality of the component Ruby. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality. CVE summarizes:
Directory traversal vulnerability in WEBrick in Ruby 1.8 before 1.8.5-p115 and 1.8.6-p114, and 1.9 through 1.9.0-1, when running on systems that support backslash (\) path separators or case-insensitive file names, allows remote attackers to access arbitrary files via (1) "..%5c" (encoded backslash) sequences or (2) filenames that match patterns in the :NondisclosureName option.
