Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The affected Ebyte product's vendor configuration utility permits access to administrative functions without verifying the operator's identity under certain credential conditions.
