Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In ZKT ZKBio CVSecurity 6.4.1_R an unauthenticated attacker can craft JWT token using the hardcoded secret to authenticate to the service console. NOTE: the Supplier disputes the significance of this report because the service console is typically only accessible from a local area network, and because access to the service console does not result in login access or data access in the context of the application software platform.
