VAR-201708-1509
Vulnerability from variot - Updated: 2025-04-20 23:15A vulnerability was discovered in Siemens OZW672 (all versions) and OZW772 (all versions) that could allow an attacker with access to port 21/tcp to access or alter historical measurement data stored on the device. Siemens OZW672 and OZW772 Contains vulnerabilities related to authorization, permissions, and access control.Information may be obtained and information may be altered. Both Siemens OZW672 and OZW772 are building controller products from Siemens AG. There are data read and write vulnerabilities in Siemens OZW672 and OZW772. An attacker can exploit these issues to bypass the authentication mechanism and perform unauthorized actions. This may aid in further attacks. A security vulnerability exists in Siemens OZW672 and OZW772 devices
