The software uses external input to construct a pathname that
					should be within a restricted directory, but it does not properly neutralize
					"..\" 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 the canonical manipulation for operating systems
						that use "\" as directory separators, such as Windows. However, it is also
						useful for bypassing path traversal protection schemes that only assume that
						the "/" separator is valid.
