CVE-2022-4991
A user who can place a specially-crafted openssl.cnf file at an appropriate path may be able to achieve arbitrary code execution with SYSTEM privileges.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
