Directory traversal vulnerability in CommuniGate Pro 4.0b4 and possibly earlier versions allows remote attackers to list the contents of the WebUser directory and its parent directory via a (1) .. (dot dot) or (2) . (dot) in a URL. NOTE: it is not clear whether this issue reveals any more information regarding directory structure than is already available to any CommuniGate Pro user, although there is a possibility that it could be used to infer product version 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.
