⚠️ Siemens reported an authentication bypass vulnerability in the RUGGEDCOM ROX II family that permits bypassing authentication via the device Built-In-Self-Test (BIST) mode. An attacker with physical serial access could obtain a root shell (CVE-2025-40761); a CVSS v4 base score of 8.6 has been assigned. No patch is available; recommended mitigations include setting secure boot passwords and isolating devices from untrusted networks.

🛡️ Rockwell Automation's FactoryTalk Viewpoint (version 14.00 and earlier) contains a privilege-escalation vulnerability tracked as CVE-2025-7973 that arises from improper handling of MSI repair operations. An attacker who can trigger a repair can hijack the SYSTEM-run cscript.exe console to spawn an elevated command prompt, enabling full privilege escalation; CVSS v4 is 8.5 (low attack complexity). Update to 15.00 or apply vendor-recommended mitigations; the issue is not remotely exploitable and no public exploitation has been reported.

🔒 CISA and international partners released new guidance to help operational technology (OT) owners and operators establish and maintain comprehensive asset inventories and taxonomies. The resource provides practical steps to identify, classify, and track OT devices and components that support critical infrastructure, including industrial control systems and automation. Implementing these practices aligns with the Cross-Sector Cybersecurity Performance Goals and enhances visibility, risk management, and operational resilience for mission-critical services.
