CISA ICS advisories warn of critical authentication and RCE flaws in industrial and IoT devices
CISA published multiple ICS advisories warning of high-severity vulnerabilities affecting industrial/IoT products deployed in critical infrastructure environments. For Jinan USR IOT Technology (PUSR) USR-W610 (<= 3.1.1.0), CISA reported multiple issues (including CVE-2026-25715, CVE-2026-24455, CVE-2026-26049, CVE-2026-26048) that could allow authentication to be effectively disabled (e.g., permitting blank admin credentials over the web interface and Telnet), enable credential exposure (including administrator credentials), and cause denial-of-service; one of the cited conditions results in full administrative control for a network-adjacent attacker without valid credentials (CVSS v3.1 9.8). Separately, EnOcean SmartServer IoT (<= 4.60.009) was reported vulnerable to OS command execution via crafted LON IP-852 management messages (CVE-2026-20761) and an additional weakness that could leak memory and help bypass mitigations such as ASLR (CVE-2026-22885) (CVSS v3.1 8.1).
CISA also warned that Welker OdorEyes EcoSystem Pulse Bypass System with XL4 Controller is affected by CVE-2026-24790 (missing authentication for a critical function), where the underlying PLC can be remotely influenced without proper safeguards, creating risk of over- or under-odorization events (CVSS v3.1 8.2). In parallel reporting, a separate CISA warning covered Honeywell CCTV products impacted by CVE-2026-1670 (CVSS 9.8), where an unauthenticated API endpoint could allow an attacker to change the “forgot password” recovery email and take over accounts to access camera feeds; at the time of reporting, there were no public exploitation reports, and CISA recommended reducing exposure (e.g., isolating devices behind firewalls and using secure remote access).

CISA ICS Advisories Highlight Multiple High-Impact Vulnerabilities Across Industrial and IoT Products
CISA published multiple Industrial Control Systems (ICS) advisories detailing vulnerabilities across a range of OT and connected-device products, including **critical** issues in *AVEVA Process Optimization* (multiple CVEs) that could enable unauthenticated **remote code execution**, SQL injection, privilege escalation, and sensitive data exposure in affected versions (<=2024.1). Additional advisories describe flaws in several **Siemens** product lines, including a DoS condition in **SIMATIC/SIPLUS ET 200** components triggered via an S7 protocol disconnect request (`CVE-2025-40944`), a TLS certificate upload input-validation issue that can crash/reboot **RUGGEDCOM ROS** devices (`CVE-2025-40935`), a local privilege escalation in **TeleControl Server Basic** prior to V3.1.2.4 (`CVE-2025-40942`), and multiple issues in **SINEC Security Monitor** (including improper authorization in `ssmctl-client` file transfer and report-generation DoS; `CVE-2025-40830`, `CVE-2025-40831`). CISA also noted vulnerabilities affecting **Siemens Industrial Edge** ecosystems, including an authorization bypass in the **Industrial Edge Device Kit** (`CVE-2025-40805`) and authentication enforcement weaknesses on specific API endpoints in **Industrial Edge Devices** that could allow impersonation if an attacker knows a legitimate user identity. Other CISA advisories covered **Schneider Electric EcoStruxure Power Build Rapsody** (`CVE-2025-13844`), where importing a malicious project file (SSD) could trigger memory corruption (e.g., double free/use-after-free) and potentially arbitrary code execution, and **Rockwell Automation FactoryTalk DataMosaix Private Cloud** (`CVE-2025-12807`), where low-privilege users could perform sensitive database operations via exposed API endpoints (SQL injection class). Separately, CISA warned about **YoSmart/YoLink** weaknesses (multiple CVEs) including insufficient authorization controls in the MQTT broker enabling cross-account device control when device IDs are obtained (with IDs described as predictable), plus additional issues such as cleartext transmission and predictable identifiers. A non-CISA item in the set reported Cisco releasing updates for a max-severity **AsyncOS** vulnerability under active exploitation (`CVE-2025-20393`) affecting *Secure Email Gateway* and *Secure Email and Web Manager* appliances, including evidence of attacker-installed persistence and attribution by Cisco Talos to **UAT-9686**; this is a separate enterprise email-security incident and not part of the ICS advisory set.

Rising ICS Vulnerability Volume and New High-Severity Advisories for Valmet and Honeywell Products
Industrial control system (ICS) vulnerability reporting hit record levels in 2025, with **508 ICS advisories** covering **2,155 CVEs** and an increasing average severity (CVSS averages exceeding **8.0** in 2024–2025), according to a Forescout report. The report highlights that **Purdue Level 1 devices** (e.g., PLCs/RTUs/IEDs) were most affected, followed by Level 3 operational systems and Level 2 control systems, with **critical manufacturing and energy** most impacted. It also flags a growing visibility gap as an increasing number of ICS vulnerabilities lack associated **CISA ICSA** publications, including changes in how some vendor advisories (e.g., Siemens) are routed. CISA published an ICS advisory for **Valmet DNA Engineering Web Tools** (<= `C2022`) describing **CVE-2025-15577**, a **high-severity path traversal** issue (CVSS 3.1 **8.6**) that could allow an **unauthenticated attacker** to manipulate a web maintenance services URL to achieve **arbitrary file read**. Separately, CISA also warned (as reported by BleepingComputer) of a **critical** authentication flaw in multiple **Honeywell CCTV** products, **CVE-2026-1670** (CVSS **9.8**), where an exposed unauthenticated API endpoint could let an attacker change the “forgot password” recovery email and potentially enable **account takeover** and **unauthorized camera feed access**; CISA reported no known public exploitation at the time and reiterated standard ICS/OT hardening guidance (reduce exposure, segment networks, and secure remote access).

CISA ICS advisories flag critical missing-authentication flaws in industrial and broadcast devices
CISA published ICS advisories warning of **critical “missing authentication for critical function”** weaknesses (CWE-306) that expose device management/control interfaces to unauthenticated access. **Synectix LAN 232 TRIO** (3-port serial-to-Ethernet adapter) is affected in **all versions** under **CVE-2026-1633** with **CVSS 3.1 10.0**, enabling unauthenticated attackers to **modify critical device settings** or **factory reset** the device. **Avation Light Engine Pro** is also affected in **all versions** under **CVE-2026-1341** with **CVSS 3.1 9.8**, allowing an attacker to **take full control** of the device due to an exposed configuration/control interface without authentication. Separate reporting highlighted a similar CISA alert for **KiloView Encoder Series** devices, tracked as **CVE-2026-1453** with **CVSS 9.8**, where missing authentication allows unauthenticated users to perform administrative actions such as **creating or deleting administrator accounts**, potentially granting full administrative control and enabling disruption or hijacking of broadcast/streaming workflows. The KiloView issue was described as affecting multiple Encoder Series models and specific firmware/hardware combinations (e.g., E1/E1-s/E2 with listed firmware versions), reinforcing the broader risk of internet- or enterprise-exposed device management planes lacking access control.
