CVE-2018-5399 Detail

Current Description

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.

Severity



CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  9.8 CRITICAL
Vector:  CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Nist CVSS score does not match with CNA score
CNA:  CERT/CC
Base Score:  9.4 CRITICAL
Vector:  CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
