- An authorization bypass vulnerability exists in the web-based management interface due to insufficient authorization checks.

(CVE-2021-1302)

- An authorization bypass vulnerability exists in the web-based management interface SSH console due to insufficient authorization checks. An authenticated, remote attacker can exploit this, by logging into the web-based management interface and using the SSH console feature, to access sensitive information that allows the attacker to carry out further attacks. (CVE-2021-1304)

- An authorization bypass vulnerability exists in the web-based management interface due to insufficient authorization checks. An authenticated, remote attacker can exploit this, by logging into the web-based management interface with a low-privileged user account, to access information such as logs, configurations, and device information that they are not authorized to view.
