Siemens, Schneider Electric, Phoenix Contact, Honeywell, and CISA released August 2026 advisories for multiple ICS and building management product vulnerabilities, including code execution, privilege escalation, and denial-of-service flaws. The most severe issues affect Siemens Simatic IoT2050 Advanced and Siveillance Video Management Servers, while Phoenix Contact and Schneider Electric also patched critical...

An unauthenticated denial-of-service vulnerability in the device's PLCnext Engineer communication interface allow an remote attacker to interrupt access via the client application. Successful exploitation prevents communication until the PLCnext service is manually restarted.

TL;DR Phoenix Contact disclosed three vulnerabilities in PLCnext firmware on August 12, 2026. One flaw, CVE-2025-41771, lets a low-privileged attacker execute unauthorized SQL queries. A second, critical bug scores a CVSS 9.8 and allows remote code execution. Why it matters PLCnext controllers run factory and infrastructure automation. So flaws here can disrupt physical processes. The most severe bug needs no login at all.

Nozomi warns that privilege-escalation flaws in Phoenix Contact PLCnext controllers could enable attackers to gain root access.
