CVE-2026-67367Network attack vector

Unauthenticated file read via HTTP path traversal

Published Sep 8, 2026 · Updated Sep 9, 2026

Path traversal in Siemens SIMOVE Fleetmanager and SIPLANT allows remote attackers to read operating-system files without authentication. The embedded HTTP server's file-serving endpoint fails to validate and neutralize directory traversal sequences before resolving requested paths. Network access to the endpoint requires no credentials, exposing files outside the intended web root, including configuration secrets, private keys, and credential stores.
