Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.57%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

An issue was discovered on Libre Wireless LS9 LS1.5/p7040 devices. There is a Authentication Bypass in the Web Interface. This interface does not properly restrict access to internal functionality. Despite presenting a password login page on first access, authentication is not required to access privileged functionality. As such, it's possible to directly access APIs that should not be exposed to an unauthenticated user.
