CVE-2023-29128Network attack vector

Privileged database-file writes via upload path traversal

Published May 9, 2023 · Updated Jan 28, 2025

Path traversal in Siemens SIMATIC Cloud Connect 7 CC712 and CC716 2.0 through before 2.1 allows remote authenticated users to write .db files. The web-management upload handler fails to confine an attacker-supplied filename to its intended directory. Privileged management access is required, and successful exploitation can alter database files or interrupt device operation.
