Ruby WEBrick directory traversal
| ruby-webrick-directory-traversal (41010) |  Medium Risk |
Description:
Ruby could allow a remote attacker to traverse directories on the system, caused by an error in the WEBrick library. An attacker could send a specially-crafted URL request containing an encoded backslash (..%5c) or files that match patterns specified in the :NondisclosureName option to view arbitrary files on the system.
