Directory traversal vulnerability in the _serve_request_multiple function in lib/Perlbal/ClientHTTPBase.pm in Perlbal before 1.70, when concat get is enabled, allows remote attackers to read arbitrary files in a parent directory via a directory traversal sequence in an unspecified parameter. NOTE: some of these details are obtained from third party information.
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.
