CVE-2024-53832

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.

Summary		(es) Se ha identificado una vulnerabilidad en CPCI85 Central Processing/Communication (Todas las versiones anteriores a V05.30). Los dispositivos afectados contienen un elemento seguro que está conectado a través de un bus SPI no cifrado. Esto podría permitir que un atacante con acceso físico al bus SPI observe la contraseña utilizada para la autenticación del elemento seguro y luego utilice el elemento seguro como un oráculo para descifrar todos los archivos de actualización cifrados.
