An issue was discovered on Topcon Positioning Net-G5 GNSS Receiver devices with firmware 5.2.2. The web interface of the product is protected by a login. A guest is allowed to login. Once logged in as a guest, an attacker can browse a URL to read the password of the administrative user. The same procedure allows a regular user to gain administrative privileges. The guest login is possible in the default configuration.
The web application does not adequately enforce appropriate authorization on all restricted URLs, scripts, or files.
