A path traversal vulnerability exists in Sage FRP 1000 before November 2019. This allows remote unauthenticated attackers to access files outside of the web tree via a crafted URL.
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.
