• Some pages that should only be accessible by a privileged user can also be accessed by a non-privileged user. This vulnerability could be exploited by an attacker with network access and valid credentials for the web interface. No user interaction is required. Exploitation could allow an attacker to access information they should not be able to read. The information affected by this vulnerability does not include passwords.
  (CVE-2019-13919)

• Some parts of the web application are not protected against cross-site request forgery (CSRF) attacks. This vulnerability could be exploited by an attacker who is able to trigger requests of a logged-in user to the application. Exploitation could allow switching the connectivity state of a user or a device.
  (CVE-2019-13920)
