How to Test-Drive Windows Server 2025’s New Security and Hybrid Features Before Upgrading
Microsoft's refreshed Windows Server 2025 Evaluation Center listing provides a 180-day trial ISO for Standard and Datacenter editions. IT teams can test new security defaults, hybrid management via Azure Arc, and infrastructure upgrades like GPU partitioning before committing to production, but must plan carefully around installation mode choices and conversion limitations.
Urgent Update: Patch These Rockwell ControlLogix Modules Now, Or Face Network Disruption
CISA released a high-severity advisory for Rockwell Automation ControlLogix EtherNet/IP modules. The denial-of-service flaw (CVE-2026-9653) affects EN2, EN3, and the discontinued ENBT. While newer modules get firmware V12.002, the ENBT has no fix, forcing owners to either replace the hardware or implement strict network isolation. Plant teams should inventory affected devices, patch immediately where possible, and plan replacements for unsupported legacy hardware.
AutomationDirect Ships Productivity Suite v4.7.0.47 to Plug Six Security Holes, Two Let Attackers Hijack Kernels
AutomationDirect released Productivity Suite v4.7.0.47 to fix six vulnerabilities reported by CISA, including two high-severity out-of-bounds write flaws that can let local attackers escalate privileges or crash the system. The flaws affect all versions up to 4.6.2.2 and are not remotely exploitable, but industrial workstations with broad physical and user access remain at risk. A six-step remediation plan covers inventory, update deployment, and ongoing asset management to close the gaps.
Patch Now: Rockwell Arena Simulation Software Harbors Four Code-Execution Flaws
Rockwell Automation has released Arena 17.00.01 to patch four out-of-bounds write vulnerabilities (CVE-2026-8085, CVE-2026-8312, CVE-2026-8313, CVE-2026-8314) that allow arbitrary code execution when a user opens a malicious file. All versions through 17.00.00 are affected, and the update is the only remediation. No active exploits were reported at the time of the July 2026 CISA advisory, but industrial users should patch immediately and apply least-privilege and segmentation controls.
A Simple Housekeeping Request Can Crash NASA's Core Flight Software — Patch Ready
CISA's advisory for CVE-2026-15352 warns that a routine Housekeeping Telemetry request can crash NASA's Core Flight System Health & Safety application, causing denial of service. The fix is updating to version 7.0.1, released in May 2026. While the software primarily runs on Linux flight hardware, Windows administrators involved in development, testing, or monitoring cFS environments should inventory their systems, restrict network access, and apply the patch to prevent disruptions.
FactoryTalk DataMosaix stored XSS could lead to account takeover — patch now
Rockwell Automation has patched a stored cross-site scripting vulnerability (CVE-2026-9292) in FactoryTalk DataMosaix Private Cloud that lets a high-privilege attacker inject malicious scripts into Workflow configurations, later executing in other users’ browsers. Affected versions 8.02 and earlier should be upgraded to 8.03 immediately to prevent account takeover, credential theft, or session hijacking. No public exploitation is known, but the patch is the only complete fix.
