Successful exploitation of these vulnerabilities could cause a denial-of-service condition.
The following version of e-mesh EMS, an optimizer software for energy resources, is affected:
A vulnerability exists in a specific Node.js function, which could allow various kinds of memory corruption and cause a denial-of-service condition.
CVE-2020-8174 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H).
The affected product version of Node.js is vulnerable to a Use After Free bug in its TLS implementation. This could cause corruption of memory leading to a denial-of-service condition.
CVE-2020-8265 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H).
The affected product version of Node.js is vulnerable to an error in the HTTP/2 session frame, which is limited to 32 settings by default. An attacker could consume all available CPU resources causing a denial-of-service condition.
CVE-2020-11080 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:N/I:N/A:H).
The affected product version of Node.js is affected by too many connection attempts with an unknown protocol. This could allow an attacker to cause a denial-of-service condition.
CVE-2021-22883 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:N/I:N/A:H).
Hitachi Energy reported these vulnerabilities to CISA.
Hitachi Energy recommends users update to e-mesh EMS 1.0.1 or later.
Hitachi Energy recommends the following security practices and firewall configurations to help protect process control networks from attacks that originate from outside the network:
Please see Hitachi Energy advisory 8DBD000077 for additional mitigation and updated information.
For additional information and access to updated firmware, please contact the Hitachi Energy service organization.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
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 cisa.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 cisa.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.
