CVE-2019-13549
The authentication mechanism on affected systems does not provide a sufficient level of protection against unauthorized configuration changes.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.03%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
