CVE-2019-14302

Full device control via exposed serial connector

Published Jan 10, 2020 · Updated Aug 5, 2024

Hardware debug interface exposure in Ricoh SP C250DN 1.06 allows physically proximate attackers to gain full control of the device. The exposed hardware serial connector opens a shell that reads and writes RAM and invokes functions at attacker-selected memory addresses. Physical access to the printer is required, after which the interface permits sensitive-data retrieval, settings changes, arbitrary code execution, or device disablement.
