An open port used for debugging grants root access to the device without access control via network.
Security researchers at ESET have reported a vulnerability called Kr00k (CVE-2019- 15126) which affects encrypted WiFi traffic for devices using Broadcom or Cypress chipsets. The vulnerability may allow an attacker to decrypt some WPA2- Personal/Enterprise traffic by forcing an AP/client to start utilizing an all-zero encryption key (similar to KRACK vulnerability).
If the software runs as a service, a user with limited access can gain administrator privileges by starting a shell with administrator rights from the Import / Export configuration dialog.

The installation path of the application is configured to have insecure permissions which allows any unprivileged user to write arbitrary files to the installation directory where all the configuration files and binaries of the service are located.
An attacker needs an authorized login on the device in order to exploit the herein mentioned vulnerabilities.
The reported vulnerabilities allow a local attacker with valid login credentials who is able to create files on the device to change the devices settings, e.g. default gateway address, time server etc. and potentially execute code.
An attacker needs an authorized login with administrative privileges on the device in order to exploit the herein mentioned vulnerability.
The weakness allows an attacker which has admin privileges on the device to redirect to his own Azure cloud account and install malicious software with the firmware update functionality.
