Directory traversal vulnerability in 2X TFTP service (TFTPd.exe) 3.2.0.0 and earlier in 2X ThinClientServer 5.0_sp1-r3497 and earlier allows remote attackers to read or overwrite arbitrary files via a ... (dot dot dot) in the filename.
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.
