CVE-2023-30561

Data interception and modification via unencrypted IUI bus

Published Jul 13, 2023 · Updated Oct 22, 2024

Missing encryption in the IUI bus of BD Alaris PCU Model 8015 12.1.3 and earlier allows attackers to read or modify module data. The PCU exchanges infusion data with attached modules over the IUI bus without cryptographic confidentiality or integrity protection. Physical access, a specially crafted device, and an active infusion are required; exploitation is confined to reading or changing bus data.
