The vulnerability is due to that the software 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 software does not properly validate the pathname. Successful exploit could allow the attacker to access a location that is outside of the restricted directory by a crafted filename.
