Security researchers have disclosed two new vulnerabilities affecting Schneider Electric Modicon programmable logic controllers (PLCs) that could allow for authentication bypass and remote code execution. The flaws, tracked as  CVE-2022-45788  (CVSS score: 7.5) and  CVE-2022-45789  (CVSS score: 8.1), are part of a  broader collection  of  security defects  tracked by Forescout as OT:ICEFALL. Successful exploitation of the bugs could enable an adversary to execute unauthorized code, denial-of-service, or disclosure of sensitive information. The cybersecurity company said the shortcomings can be chained by a threat actor with known flaws from other vendors (e.g.,  CVE-2021-31886 ) to achieve deep lateral movement in operational technology (OT) networks. "Deep lateral movement lets attackers gain deep access to industrial control systems and cross often overlooked security perimeters, allowing them to perform highly granular and stealthy ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) last week published an industrial control system ( ICS ) advisory related to multiple vulnerabilities impacting Schneider Electric's  Easergy  medium voltage protection relays. "Successful exploitation of these vulnerabilities may disclose device credentials, cause a denial-of-service condition, device reboot, or allow an attacker to gain full control of the relay," the agency  said  in a bulletin on February 24, 2022. "This could result in loss of protection to your electrical network." The two high-severity weaknesses impact Easergy P3 versions prior to v30.205 and Easergy P5 versions before v01.401.101. Details of the flaws are as follows – CVE-2022-22722  (CVSS score: 7.5) – Use of hardcoded credentials that could be abused to observe and manipulate traffic associated with the device. CVE-2022-22723  and  CVE-2022-22725  (CVSS score: 8.8) – A buffer overflow vulnerability ...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
