CVE-2025-40573

Configuration overwrite via backup restore path traversal

Published May 13, 2025 · Updated Jul 8, 2025

Path traversal in Siemens SCALANCE LPE9403 before 4.0 HF0 allows local users with administrator rights to restore unintended files. The backup restore function accepts traversal sequences that resolve a selected file outside the designated backup directory instead of enforcing containment. A restored backup replaces configuration files under /etc; the path is restricted to privileged local users, with no reported data disclosure or service interruption.
