An attacker could exploit this vulnerability by first gaining access to credentials of any account or have access to a session ticket issued for an account. After gaining access via the configuration tool that accesses the proprietary Open Data-base Connectivity (ODBC) protocol (TCP 2102), the database table can be manipulated for privilege escalation, which then allows unauthorized modification or permanent disabling of the device. CVE-2021-35534 has been assigned to this vulnerability. A CVSS v3 base score of 7.2 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
