2. RISK EVALUATION
Successful exploitation of these vulnerabilities could allow a remote attacker
to gain root access to the underlying operating system of the device and may
allow read/write access.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of RP210E and DCU 210, a remote panel and digital
control unit, are affected:
o RP210E Versions 3.7 and prior
o DCU210E Versions 3.7 and prior
3.2 VULNERABILITY OVERVIEW
3.2.1 CLEARTEXT TRANSMISSION OF SENSITIVE INFORMATION CWE-319
The embedded web server software transmits sensitive or security-critical data
in cleartext in a communication channel that can be sniffed by unauthorized
actors.
CVE-2018-5402 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:N/A:N ).
3.2.2 CLEARTEXT TRANSMISSION OF SENSITIVE INFORMATION CWE-319
The device software transmits sensitive or security-critical data in cleartext
in a communication channel that can be sniffed by unauthorized actors.
CVE-2018-5401 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:N/A:N ).
3.2.3 ORIGIN VALIDATION ERROR CWE-346
The software does not properly verify that the source of data or communication
is valid.
CVE-2018-5400 has been assigned to this vulnerability. A CVSS v3 base score of
9.1 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:N/A:H ).
3.2.4 USE OF HARD-CODED CREDENTIALS CWE-798
The software contains hard-coded credentials, such as a password or
cryptographic key, which it uses for its own inbound authentication, outbound
communication to external components, or encryption of internal data.
CVE-2018-5399 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
3.2.5 WEAK PASSWORD RECOVERY MECHANISM FOR FORGOTTEN PASSWORD CWE-640
The software contains a mechanism for users to recover or change their
passwords without knowing the original password, but the mechanism is weak.
CVE-2019-6560 has been assigned to this vulnerability. A CVSS v3 base score of
8.2 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:N/A:L ).
3.2.6 WEAK PASSWORD REQUIREMENTS CWE-521
The product contains multiple weak password requirements, which makes it easier
for attackers to compromise user accounts.
CVE-2019-6558 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:N/A:N ).

4. MITIGATIONS
Auto-Maskin reports new firmware is available to download from its website that
mitigates the reported vulnerabilities.
CISA recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability. Specifically, users should:
o Minimize network exposure for all control system devices and/or systems,
and ensure that they are not accessible from the Internet .
o Locate control system networks and remote devices behind firewalls, and
isolate them from the business network.
o When remote access is required, use secure methods, such as Virtual Private
Networks (VPNs), recognizing that VPNs may have vulnerabilities and should
be updated to the most current version available. Also recognize that VPN
is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices
on the ICS webpage on us-cert.gov . Several recommended practices are available
for reading and download, including Improving Industrial Control Systems
Cybersecurity with Defense-in-Depth Strategies .
Additional mitigation guidance and recommended practices are publicly available
on the ICS webpage on us-cert.gov in the Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies .
Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to CISA for tracking
and correlation against other incidents.
No known public exploits specifically target these vulnerabilities.
