The affected products have an unauthenticated stored cross-site scripting vulnerability in the embedded webserver. The payload is transferred to the controller over simple network management protocol (SNMP) and is rendered on the homepage of the embedded website. Exploitation of this vulnerability could result in unauthenticated remote code execution.CVE-2022-46670 has been assigned to this vulnerability. A CVSS v3 base score of 7.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L). The affected products have a clickjacking vulnerability where an attacker with network access to the affected systems could send TCP packets to the webserver, closing it abruptly. This could cause a denial-of-service condition for the web server application on the device.CVE-2022-3166 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
