CVE-2021-33885Network attack vector

Unauthenticated command execution via unsigned critical data

Published Aug 25, 2021 · Updated Aug 4, 2024

Insufficient data-authenticity verification in B. Braun SpaceCom2 before 012U000062 allows remote attackers to execute system commands. SpaceCom2 accepts critical data sets without cryptographic signatures and substitutes attacker-supplied content for trusted device data. Exploitation requires network access and a connected infusion pump that is turned off or in standby; an active therapy cannot be changed.
