CVE-2023-29103Network attack vector

Protected-data disclosure via hard-coded diagnostic password

Published May 9, 2023 · Updated Jan 28, 2025

Hard-coded credentials in Siemens SIMATIC Cloud Connect 7 CC712 and CC716 before 2.1 allow remote authenticated users to read diagnostic files. The device applies an embedded password as the protection control for diagnostic files instead of using a device-specific secret. Network access with low privileges is required, and the documented consequence is limited to disclosure of the protected contents.
