The U.S. Cybersecurity and Infrastructure Security Company (CISA) very last 7 days posted an industrial handle procedure (ICS) advisory relevant to numerous vulnerabilities impacting Schneider Electric’s Easergy medium voltage protection relays.
“Thriving exploitation of these vulnerabilities could disclose gadget qualifications, lead to a denial-of-support affliction, device reboot, or allow an attacker to achieve entire command of the relay,” the company reported in a bulletin on February 24, 2022. “This could result in loss of defense to your electrical network.”

The two large-severity weaknesses affect Easergy P3 variations prior to v30.205 and Easergy P5 versions ahead of v01.401.101. Facts of the flaws are as follows –
- CVE-2022-22722 (CVSS score: 7.5) – Use of hardcoded qualifications that could be abused to notice and manipulate website traffic connected with the gadget.
- CVE-2022-22723 and CVE-2022-22725 (CVSS rating: 8.8) – A buffer overflow vulnerability that could result in method crashes and execution of arbitrary code by sending specially crafted packets to the relay above the network.

Moreover, Dragos discovered malicious exercise from a few new groups that were being identified concentrating on ICS methods last calendar year, such as from that of actors it tracks as Kostovite, Erythrite, and Petrovite, just about every of which focused the OT environments of renewable vitality, electrical utility, and mining and power corporations found in Canada, Kazakhstan, and the U.S.
