CVE-2023-0776
Baicells Nova 436Q, Nova 430E, Nova 430I, and Neutrino 430 LTE TDD eNodeB devices with firmware through QRTB 2.12.7 are vulnerable to remote shell code exploitation via HTTP command injections.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.19%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
