Description

Siemens, Schneider Electric, and Phoenix Contact have released their July 2025 Patch Tuesday security updates, addressing various vulnerabilities in industrial control systems (ICS). Siemens issued nine advisories, including a warning urging operators to improve system security amid rising geopolitical tensions and cyber threats potentially linked to Iran. Critical vulnerabilities in the Sinec NMS platform were patched to prevent privilege escalation and remote code execution. Siemens also fixed high-severity flaws in products like TIA Administrator, Sicam Toolbox II, Solid Edge, Ruggedcom ROS, and Simatic CN 4100. Additionally, medium-risk issues in Siprotect 5, TIA Portal, and TIA Project Server were resolved. Schneider Electric released four security advisories. One advisory outlined multiple critical flaws in the EcoStruxure IT Data Center Expert solution, which attackers could exploit to execute code remotely, escalate privileges, or obtain the root password without authentication. Another bulletin focused on a data exposure vulnerability in both EcoStruxure Power Monitor Expert and Power Operation. The final two advisories involved vulnerabilities introduced through third-party components affecting EcoStruxure Power Operation and older-generation industrial PC systems. Phoenix Contact released four advisories as well. Two of them revealed serious issues in PLCnext firmware that could allow attackers to reboot systems, execute files, or trigger denial-of-service (DoS) conditions. The other two advisories cover vulnerabilities in Charx EV charging controllers, including risks of unauthorized access, privilege escalation, and read/write manipulation. These advisories were also made available by Germany’s VDE CERT. In the U.S., CISA disclosed vulnerabilities in Emerson ValveLink devices, while earlier alerts were shared by ABB and Mitsubishi Electric.
