The Meinberg SyncBox/PTP/PTPv2 devices have default SSH keys which allow attackers to get root access to the devices. All firmware versions up to v5.34o, v5.34s, v5.32 or 5.34g are affected. The private key is also used in an internal interface of another Meinberg Device and can be extracted from a firmware update of this device. An update to fix the vulnerability was published by the vendor.
