What it is
CGI versions before 5.00 for Perl return upload filenames with any client-supplied path, including ../ and Windows paths. The name returned for an uploaded file is the filename parameter of the part's Content-Disposition header, unchanged. An application that saves the upload under this name can be made to write outside the intended directory.
