Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
Description
A vulnerability has been identified in CPCI85 Central Processing/Communication (All versions < V05.30). The affected devices contain a secure element which is connected via an unencrypted SPI bus. This could allow an attacker with physical access to the SPI bus to observe the password used for the secure element authentication, and then use the secure element as an oracle to decrypt all encrypted update files.
