The Auto-Maskin DCU 210E firmware contains an undocumented Dropbear SSH server, v2015.55, configured to listen on Port 22 while the DCU is running. The Dropbear server is configured with a hard-coded user name and password combination of root / amroot. The server is configured to use password only authentication not cryptographic keys, however the firmware image contains an RSA host-key for the server. An attacker can exploit this vulnerability to gain root access to the Angstrom Linux operating system and modify any binaries or configuration files in the firmware. Affected releases are Auto-Maskin DCU-210E RP-210E: Versions prior to 3.7 on ARMv7.

The Auto-Maskin DCU 210E, RP-210E, and Marine Pro Observer Android App use an embedded webserver that uses unencrypted plaintext for the transmission of the administrator PIN Impact: An attacker once authenticated can change configurations, upload new configuration files, and upload executable code via file upload for firmware updates. Requires access to the network. Affected releases are Auto-Maskin DCU-210E, RP-210E, and the Marine Pro Observer Android App. Versions prior to 3.7 on ARMv7.

In Auto-Maskin RP210E Versions 3.7 and prior, DCU210E Versions 3.7 and prior and Marine Observer Pro (Android App), the software contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.
