CVE-2021-33885: Bbraun spacecom2 improper verification of cryptographic signature vulnerability

Bbraun · Spacecom2

An Insufficient Verification of Data Authenticity vulnerability in B. Braun SpaceCom2 prior to 012U000062 allows a remote unauthenticated attacker to send the device malicious data that will be used in place of the correct data. This results in full system command access and execution because of the lack of cryptographic signatures on critical data sets.
