CVE-2021-27944
Several high privileged APIs on the Vizio P65-F1 6.0.31.4-2 and E50x-E1 10.0.31.4-2 Smart TVs do not enforce access controls, allowing an unauthenticated threat actor to access privileged functionality, leading to OS command execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.54%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
