Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

CWE-306: Missing Authentication for Critical Function in the ait.core.server telemetry and command broker (ait-server) in NASA-AMMOS AIT-Core through 3.1.1 allows an unauthenticated remote attacker with network access to the ZeroMQ message bus to inject spacecraft command data, exfiltrate command and telemetry traffic, inject forged telemetry, or disrupt the command and telemetry bus. The ait-server ZeroMQ broker binds its XSUB and XPUB sockets to all network interfaces by default without authentication or transport security. An attacker able to reach TCP port 5559 can publish messages onto internal topics, including the __commands__ command topic. With the shipped default configuration, command messages are forwarded through command_stream and emitted on the command-uplink UDP path. An attacker able to reach TCP port 5560 can subscribe to command and telemetry traffic on the ground bus. AIT-Core 3.1.2 changes the default ZeroMQ bind addresses to loopback.
