CVE-2023-23773
The Motorola MBTS Base Radio lacks cryptographic signature validation for firmware update packages, allowing an authenticated attacker to gain arbitrary code execution, extract secret key material, and/or leave a persistent implant on the device.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
