An issue was discovered on Topcon Positioning Net-G5 GNSS Receiver devices with firmware 5.2.2. The web interface of the product has a local file inclusion vulnerability. An attacker with administrative privileges can craft a special URL to read arbitrary files from the device's files system.
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.
