CVSS 10.0 Flaw
Critical flaw in Siemens OZW Web Servers Enable Unauthenticated RCE

Siemens issued a security advisory (SSA-047424) for two serious vulnerabilities—CVE-2025-26389 and CVE-2025-26390—impacting the OZW672 and OZW772 web servers. These servers are commonly used for remote monitoring and controlling building systems like heating and air conditioning. Both vulnerabilities can be exploited without authentication, potentially compromising the entire system.

“OZW672 and OZW772 Web Server versions contain vulnerabilities that could allow an attacker to execute arbitrary code on the device with root privileges… or to authenticate as Administrator user,” Siemens warned.
