AMMOS Instrument Toolkit (AIT) GUI before 2.5.1 contains a missing authentication vulnerability that allows any unauthenticated network attacker to obtain a valid session and issue arbitrary spacecraft commands by calling Sessions.create() without any credential check. Attackers can exploit the unauthenticated session issuance in Sessions.create() and subsequently invoke handle_cmd() to forward arbitrary commands directly to the AIT command bus without any authentication gate between session creation and command dispatch.
