CVE-2019-17584Network attack vector

Root access via default SSH keys

Published Jan 21, 2020 · Updated Aug 5, 2024

Authentication bypass in Meinberg SyncBox/PTP/PTPv2 firmware before 5.34o allows remote attackers to gain root access via SSH. Devices ship with a shared default SSH private key, and the same key appears in an internal interface and can be extracted from firmware updates. Exploitation requires network reachability to SSH; successful authentication grants root control of the device, including confidentiality, integrity, and availability impact.
