Sensitive information disclosure via incorrect resource permissions

Published May 13, 2025 · Updated Jul 8, 2025

Incorrect permission assignment in Siemens SCALANCE LPE9403 before V4.0 HF0 allows local users to read sensitive device information. The firmware assigns overly broad permissions to unspecified critical resources, exposing their contents to non-privileged accounts. A low-privilege local account is required; Siemens has not identified the affected resources or reported integrity or availability impact.
