CVE-2023-24022
Baicells Nova 227, Nova 233, and Nova 243 LTE TDD eNodeB devices with firmware through RTS/RTD 3.7.11.3 have hardcoded credentials that are easily discovered and can be used by remote attackers to authenticate via ssh.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.56%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
