CISA Flags 9.3 CVSS Score as Azure RTOS Bugs Expose Rockwell Micro800 PLCs to Remote Code Execution
CISA's advisory ICSA-25-226-25 warns of four high-severity vulnerabilities in Rockwell Micro800 PLCs, including three remote code execution flaws in Azure RTOS and a denial-of-service bug in CIP packet handling, scoring CVSS v4 9.3. The issues affect Micro820, Micro850, and Micro870 controllers across critical infrastructure sectors. While Rockwell provides firmware migration paths, patch availability gaps and the complexity of OT updates mean network isolation and monitoring are essential immediate responses.
Windows 11 23H2 Hits End of Life November 11: Why Gamers Now Have No Excuse to Avoid 24H2
Windows 11 23H2 Home and Pro security updates end November 11, 2025. Gamers who avoided 24H2 due to initial bugs can now upgrade safely as fixes are widely available. The enablement package model makes future transitions smoother, but the hard deadline demands immediate action to stay protected.
CVE-2025-40584: Siemens SIMOTION and SINAMICS Tools Vulnerable to XXE File Disclosure, Some Left Unpatched
Siemens disclosed an XXE vulnerability (CVE-2025-40584) in its SIMOTION SCOUT and SINAMICS STARTER engineering tools that could allow attackers to read arbitrary files from compromised hosts. While patches exist for some versions, many remain without a fix, forcing industrial organizations to rely on mitigations like avoiding untrusted XML files and network segmentation. The flaw, which requires a user to open a malicious XML file, highlights ongoing security challenges in operational technology environments.
Rockwell Studio 5000 Flaw CVE-2025-7971: Patch to v37.00.02 to Stop Environment Variable Attacks
CISA has reissued an advisory for CVE-2025-7971, a high-severity vulnerability in Rockwell Automation’s Studio 5000 Logix Designer that allows attackers with local network access to crash the software or potentially execute code via malicious environment variables. The flaw affects versions 36.00.02 through 37.00.02 and has been patched in v37.00.02; operators must update immediately and implement compensating controls, especially given the historical precedent of critical Rockwell engineering-station attacks.
Rockwell Automation Patches FactoryTalk Action Manager Vulnerability That Broadcasts API Tokens
Rockwell Automation has patched a local information disclosure vulnerability in FactoryTalk Action Manager (CVE-2025-9036) that broadcast reusable API tokens over unauthenticated WebSocket connections. Organizations must update to version 1.01 or later to prevent token capture by local attackers, which could lead to system manipulation in critical infrastructure.
Critical VNC Authentication Bypass in Siemens SINUMERIK CNC Systems—Patch Now, CISA Warns
Siemens patched CVE-2025-40743, a high-severity VNC authentication bypass in SINUMERIK CNC controllers, after researchers found that insufficient password verification could allow adjacent-network attackers to gain remote control. CISA reissued the advisory, urging immediate patching or mitigations like closing VNC ports and strengthening passwords. The flaw poses a serious risk to Windows-based operator stations that commonly serve as pivot points into OT networks.
Rockwell Patches Critical DoS Flaws in 1756-EN4TR Modules, Urges Immediate Firmware Update to 7.001
Rockwell Automation has released firmware version 7.001 to address two denial-of-service vulnerabilities in its 1756-EN4TR and EN4TRXT ControlLogix modules. The flaws, CVE-2025-8007 and CVE-2025-8008, can cause a major non-recoverable fault when malformed Forward Close messages are sent. Operators in critical manufacturing and chemical sectors are urged to patch immediately and harden network segmentation.
Siemens Energy Meters Exposed: Cleartext SMTP Passwords Threaten Utility Networks
Siemens SICAM Q100 and Q200 power meters store SMTP credentials in plaintext, tracked as CVE-2025-40752 and CVE-2025-40753. CISA urges immediate firmware updates to versions V2.62 (Q100) and V2.80 (Q200) to prevent local attackers from extracting and misusing email passwords. Operators should also rotate credentials, segment networks, and secure configuration backups.
Rockwell Patch Plugs SYSTEM Takeover Hole in FactoryTalk ViewPoint via MSI Repair Hijack
CVE-2025-7973 is a local privilege escalation flaw in Rockwell Automation's FactoryTalk ViewPoint that allows an attacker to gain SYSTEM privileges by hijacking a Windows Installer repair operation. Affected versions 14.00 and earlier must be updated to 15.00 immediately. While no active exploits are reported, the 8.5 CVSS score and critical use in ICS environments demand urgent patching, hardening of script hosts, and close monitoring of installer activity.
CISA Warns: Rockwell ArmorBlock 5000 Flaws Allow Remote Session Hijack, Score Hits 8.8
CISA has issued a high-severity advisory for two vulnerabilities in Rockwell Automation’s ArmorBlock 5000 I/O modules that allow remote session hijacking via predictable session IDs and a three-minute credential reuse window. Affected 5032-series modules with firmware 1.011 or earlier should be immediately isolated from the internet, segmented on the network, and patched as soon as vendor fixes become available. The flaws, tracked as CVE-2025-7773 and CVE-2025-7774, carry a CVSS v4 score of 8.8 and could lead to production disruption or safety risks in industrial environments.
Siemens Patches Critical Remote Exploits in SINEC Management Suite and Embedded OS, Urging Immediate ICS Updates
Siemens has patched multiple high-severity vulnerabilities in its SINEC NMS and SINEC OS products that could allow remote attackers to gain administrative control, inject code, and cascade compromises across industrial networks. With CVSS scores reaching 9.9 and a policy change that makes Siemens ProductCERT the primary source for updates, operators are urged to upgrade SINEC NMS to V4.0 and SINEC OS devices to V3.1/V3.2 immediately, while deploying compensating controls where patching must be deferred.
Microsoft Draws Line in the Sand: Windows 11 23H2 Support Ends November 11, Leaving Gamers and Enterprises With Hard Choices
