CISA Warns of Critical Flaws Affecting Industrial Appliances from Advantech and Hitachi

The U.S. Cybersecurity and Infrastructure Security Agency on Tuesday released two Industrial Control Systems advisories pertaining to severe flaws in Advantech R-SeeNet and Hitachi Energy APM Edge appliances.

Patches have been made available in version R-SeeNet version 2.4.21 released on September 30, 2022.

Also published by CISA is an update to a December 2021 advisory about multiple flaws in Hitachi Energy Transformer Asset Performance Management Edge products that could render them inaccessible.

The twin alerts come less than a week after CISA published 25 ICS advisories on October 13, 2022, spanning several vulnerabilities across devices from Siemens, Hitachi Energy, and Mitsubishi Electric.

According to OT cybersecurity and asset monitoring company SynSaber, 681 ICS product vulnerabilities were reported via CISA in the first half of 2022, out of which 152 are rated Critical, 289 are rated High, and 2015 are rated Medium in Severity.

What’s more, 54 of the Critical/High-rated CVEs have no patch or any mitigation available from the vendors, accounting for 13% of the total reported flaws and remaining “Forever-day vulnerabilities.”
