Medium 6.8
Weak/Predictable root Password
A high privileged remote attacker with admin privileges for the webUI can brute-force the "root" and "user" passwords of the underlying OS due to a weak password generation algorithm.
-
Medium 6.8
Shell access to UART Console
An attacker can use an undocumented UART port on the PCB as a side-channel to get root access e.g. with the credentials obtained from CVE-2025-41692.
-
Medium 6.5
Authenticated Denial-of-Service via Webshell
A low privileged remote attacker can run the webshell with an empty command containing whitespace. The server will then block until it receives more data, resulting in a DoS condition of the websserver.
-
Medium 4.6
Hardcoded User Password
An attacker can use an undocumented UART port on the PCB as a side-channel with the user hardcoded credentials obtained from CVE-2025-41692 to gain read access to parts of the filesystem of the device.
-
Medium 4.3
Authenticated Denial-of-Service via SSH
A low privileged remote attacker can use the ssh feature to execute commands directly after login. The process stays open and uses resources which leads to a reduced performance of the management functions. Switching functionality is not affected.
