An improper sanitization of input vulnerability in B. Braun SpaceCom2 prior to 012U000062 allows a remote unauthenticated attacker to gain user-level command-line access by passing a raw external string straight through to printf statements. The attacker is required to be on the same network as the device.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
