🛡️ Siemens reports a local privilege escalation vulnerability affecting SIMOTION Tools installers that use an affected NSIS setup component. The flaw (CWE-754) in Nullsoft Scriptable Install System (NSIS) before 3.11 can allow an unprivileged user to gain SYSTEM privileges during installation by exploiting a race condition. The issue is tracked as CVE-2025-43715 with a CVSS v3.1 base score of 8.1. No vendor fix is available yet; Siemens and CISA offer mitigations and hardening guidance.

🔒 Schneider Electric disclosed a Files or Directories Accessible to External Parties vulnerability affecting Modicon M340 devices and the BMXNOE0100/BMXNOE0110 Ethernet modules that could allow remote actors to remove files, block firmware updates, and disrupt the device webserver. The issue is tracked as CVE-2024-5056 with a CVSS v4 base score of 6.9. Schneider released firmware fixes for BMXNOE0100 (SV3.60) and BMXNOE0110 (SV6.80) and recommends immediate mitigations including network segmentation, disabling FTP when not required, and configuring Access Control Lists per the device manual. CISA also advises isolating control networks, minimizing internet exposure, and using VPNs for remote access.

⚠️ CISA published an advisory on two vulnerabilities in Schneider Electric EcoStruxure products that could enable a denial-of-service condition and the exposure of sensitive credentials. The issues are tracked as CVE-2025-8449 (uncontrolled resource consumption) and CVE-2025-8448 (sensitive information exposure). Affected Enterprise Server and Workstation versions should be updated to the fixed releases (for example 7.0.2.348, 6.0.4.10001 (CP8), 5.0.3.17009 (CP16)). If patches cannot be applied immediately, implement strong access controls, network segmentation, MFA where available, and continuous monitoring.

🔒 Siemens reported a vulnerability in Apogee PXC and Talon TC devices that allows unauthorized actors to download device database files via BACnet. Affected devices permit unauthenticated access to encrypted .db files that can contain passwords; the issue is tracked as CVE-2025-40757 with a CVSS v4 base score of 6.3. Siemens and CISA recommend changing default passwords, hardening network access, and isolating control networks. Exploitation is remotely feasible with low complexity; no public exploitation has been reported to CISA.

🔒 Open-source tools can provide a cost-effective, flexible foundation for operational technology (OT) security in industrial environments. By combining passive asset discovery, protocol-aware inspection, IDS/IPS, centralized logging and vulnerability management, organizations can approximate many capabilities of expensive commercial offerings. Recommended components include Malcolm (with Zeek), Security Onion, ELK, Wazuh and OpenVAS, augmented by asset sources like NetBox. Successful deployment requires experienced OT/IT teams or external consultants to configure, tune and maintain the stack, and is not a plug-and-play substitute for vendor support.

🔒 A newly observed ransomware group, The Gentlemen, has rapidly expanded operations across Asia Pacific, South America, the US and the Middle East since first being identified in August. Trend Micro reports the group leverages legitimate drivers, GPO abuse and custom tooling to disable endpoint security and move laterally. Victims span manufacturing, construction, healthcare and insurance, and defenders are urged to adopt zero-trust, behavioral EDR/XDR and rigorous segmentation.

🔒 Industrial digitization and interconnected production make OT security a strategic priority, as attacks on SCADA, networked machines and production data can cause outages, reputational harm and even life‑threatening incidents. Faced with budget pressure, the article explores cost‑efficient open-source alternatives that can approach commercial capability. It outlines recommended tool combinations and operational caveats.

⚠️ Rockwell Automation's CompactLogix® 5480 controllers (versions 32–37.011 with Windows package 2.1.0 on Windows 10 v1607) contain a Missing Authentication for Critical Function vulnerability (CVE-2025-9160). An attacker with physical access could abuse the controller's maintenance menu to execute arbitrary code. CVSS scores are v3: 6.8 and v4: 7.0, and CISA reports the flaw is not remotely exploitable with no public exploitation reported. Rockwell and CISA recommend applying published security best practices and minimizing network exposure.

🔒 Rockwell Automation released a security update for 1783-NATR to remediate a memory corruption issue stemming from a Wind River VxWorks calloc() allocator flaw. The vulnerability (CVE-2020-28895) can produce smaller-than-expected allocations, enabling memory corruption and potential remote exploitation with low attack complexity. Rockwell published firmware 1.007 to correct the defect; customers unable to upgrade should follow Rockwell's security best practices and apply the network and access mitigations recommended by CISA.

🔒 Rockwell Automation disclosed a vulnerability in Analytics LogixAI (versions 3.00 and 3.01) caused by an over-permissive Redis instance that can expose sensitive system information to an intranet attacker. Tracked as CVE-2025-9364, the issue carries a CVSS v3.1 score of 8.8 and a CVSS v4 score of 8.7 and may permit data access and modification when exploited from an adjacent network with low attack complexity. Rockwell has published fixes in versions 3.02 and later and advises customers to apply updates where possible; CISA reiterates standard mitigations such as minimizing network exposure, isolating control networks behind firewalls, and maintaining secure remote access practices.

⚠️ A NULL pointer dereference vulnerability (CVE-2025-9166) in Rockwell Automation ControlLogix 5580 version 35.013 can cause the controller to enter a major, nonrecoverable fault resulting in denial of service. CISA reports a CVSS v4 base score of 8.2 and notes remote exploitability with low attack complexity.
