UPDATED INFORMATION

This updated advisory is a follow-up to the original advisory titled ICSA-17-031-01 BINOM3 Electric Power Quality Meter that was published January 31, 2017, on the NCCIC/ICS-CERT web site.

AFFECTED PRODUCTS

The following BINOM3 power meters are affected:

• Universal multifunctional electric power quality meter.

IMPACT

--------- Begin Update A Part 1 of 1 --------

Successful exploitation of these vulnerabilities could cause unauthorized access to the device, sensitive information leakage, arbitrary script/code execution, unauthorized functional configuration and data changes, and denial-of-service attacks.

--------- End Update A Part 1 of 1 ----------

MITIGATION

BINOM3 has not created mitigations for these vulnerabilities.

NCCIC/ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:

• Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
• Locate control system networks and remote devices behind firewalls, and isolate them from the business network.
• 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.

ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page. 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 in the ICS‑CERT Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site.

Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.

In addition, ICS-CERT recommends that users take the following measures to protect themselves from social engineering attacks:

1. Do not click web links or open unsolicited attachments in email messages.
2. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
3. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.

No known public exploits specifically target these vulnerabilities.

VULNERABILITY OVERVIEW

Input sent from a malicious client is not properly verified by the server. An attacker can execute arbitrary script code in another user’s browser session.

CVE-2017-5164 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:H).

Lack of authentication for remote service gives access to application set up and configuration.

CVE-2017-5162 has been assigned to this vulnerability. A CVSS v3 base score of 10 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).

There is no CSRF Token generated per page and/or per (sensitive) function. Successful exploitation of this vulnerability can allow silent execution of unauthorized actions on the device such as configuration parameter changes, and saving modified configuration.

CVE-2017-5165 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:H).

This flaw can be used to gain privileged access to the device.

CVE-2017-5166 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Users do not have any option to change their own passwords.

CVE-2017-5167 has been assigned to this vulnerability. A CVSS v3 base score of 8.6 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L).
