The software uses external input to construct a pathname that
					should be within a restricted directory, but it does not properly neutralize
					'....//' (doubled dot dot slash) sequences that can resolve to a location that
					is outside of that directory.This allows attackers to traverse the file system to access files or
						directories that are outside of the restricted directory.The '....//' manipulation is useful for bypassing some path traversal
						protection schemes. If "../" is filtered in a sequential fashion, as done by
						some regular expression engines, then "....//" can collapse into the "../"
						unsafe value (CWE-182). It could also be useful when ".." is removed, if the
						operating system treats "//" and "/" as equivalent.
