CVE-2019-14475
An attacker can obtain a session ID from CVE-2019-9583, resulting in the ability to read the service messages, clear the system protocol, create a new user in the system, or modify/delete internal programs.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.97%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
