🚨 CISA published an advisory on September 23, 2025, describing high‑severity vulnerabilities in Viessmann's Vitogate 300 gateway. The advisory identifies an OS command injection (CWE‑78, CVE‑2025‑9494) and a client‑side enforcement bypass (CWE‑602, CVE‑2025‑9495) that can enable command modification or unexpected client–server interactions. A CVSS v4 base score of 8.7 is reported overall, and affected devices running versions prior to 3.1.0.1 should be upgraded. CISA notes these issues are not remotely exploitable and recommends updating to 3.1.0.1 and implementing network hardening controls.

⚠️ CISA advises that a denial-of-service vulnerability (CVE-2025-8531) affects Mitsubishi Electric MELSEC-Q Series CPU modules when the user authentication function is enabled, due to improper handling of a length parameter (CWE-130). The issue has a CVSS v3.1 base score of 6.8 (AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H) and is exploitable remotely but characterized by high attack complexity. Mitsubishi has identified fixed units with serial ranges beginning '27082' or later and recommends migrating to the successor MELSEC iQ-R Series where updates are unavailable; organizations should apply network-access restrictions and defense-in-depth mitigations.

⚠ Schneider Electric has released an update addressing a link‑following vulnerability (CVE‑2025‑5296) in SESU that could allow an authenticated, low‑privileged actor to write arbitrary data to protected locations. The issue, rated CVSS v3.1 base score 7.3, affects SESU versions prior to 3.0.12 and numerous Schneider Electric products that bundle SESU. Version 3.0.12 contains the fix; apply the update or restrict access to the installation directory and follow CISA mitigation guidance.

🔒 AutomationDirect has disclosed multiple vulnerabilities in the CLICK PLUS series affecting firmware releases prior to v3.71. Issues include cleartext credential storage, a hard-coded AES key, an insecure RSA implementation, a predictable PRNG seed, authorization bypasses, and resource exhaustion flaws. CVSS v4 severity reaches 8.7 for the most critical cryptographic and key-generation weaknesses. AutomationDirect and CISA recommend updating to v3.80 and applying network isolation, access restrictions, logging, and endpoint protections until patches are deployed.

🔒 CISA warns of a high-severity vulnerability in SunPower PVS6 inverters (CVE-2025-9696) caused by hard-coded credentials in the Bluetooth Low Energy (BLE) interface. An attacker within Bluetooth range can exploit published protocol details and fixed encryption parameters to gain full device access, and CISA reports a CVSS v4 base score of 9.4. Successful exploitation could allow firmware replacement, disabling power production, modifying grid or firewall settings, creating SSH tunnels, and manipulating attached devices. SunPower did not respond to coordination; CISA advises minimizing network exposure, isolating control systems, using secure remote access methods such as up-to-date VPNs, and applying targeted intrusion detection and ICS best practices.

⚠️ Mitsubishi Electric's MELSEC iQ-F Series CPU modules are affected by a Missing Authentication for Critical Function vulnerability (CVE-2025-7405) in Modbus/TCP that can allow remote attackers to read and write device values and potentially halt program execution. CISA assigns a CVSS v4 base score of 6.9 and notes the issue is remotely exploitable with low attack complexity. Mitsubishi reports many FX5U/FX5UC/FX5UJ/FX5S variants affected and currently has no fixed version planned. Recommended mitigations include network segmentation, VPNs or firewalls, IP filtering, and restricting physical access.

⚠️ Delta Electronics disclosed an CNCSoft-G2 out‑of‑bounds write vulnerability (CVE-2025-47728) in DPAX file parsing that can cause memory corruption and enable arbitrary code execution in the affected process. CISA assigns a CVSS v4 base score of 8.5 and notes low attack complexity but requires user interaction such as opening a malicious file or visiting a malicious page. Affected versions include v2.1.0.20 and earlier; Delta recommends updating to v2.1.0.27 or later per advisory Delta-PCSA-2025-00007. CISA advises applying the update, isolating control systems, avoiding untrusted attachments, and following ICS recommended practices; no public exploitation has been reported to date.

🔒 Mitsubishi Electric disclosed a MELSEC iQ-F Series CPU module vulnerability (CVE-2025-7731) that transmits sensitive authentication data in cleartext over SLMP, enabling remote attackers to intercept credentials and read or write device values or halt program execution. Assigned CVSS v4 8.7 and described as remotely exploitable with low attack complexity, the issue affects many FX5U/FX5UC/FX5UJ/FX5S variants — Mitsubishi reports no planned patch. Mitsubishi and CISA recommend mitigations such as encrypting SLMP traffic with a VPN, restricting LAN access, isolating control networks behind firewalls, and following ICS hardening best practices.
