An issue was discovered in Ozeki NG SMS Gateway through 4.17.6. By leveraging a path traversal vulnerability in the Autoreply module's Script Name, an attacker may write to or overwrite arbitrary files, with arbitrary content, usually with NT AUTHORITY\SYSTEM privileges.
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.
