CVE-2021-37175Network attack vector

Filesystem overview disclosure via improper traversal permissions

Published Sep 14, 2021 · Updated Aug 4, 2024

Improper access control in Siemens RUGGEDCOM ROX before 2.14.1 allows remote attackers to view the device's full filesystem layout. Device permission checks do not properly restrict filesystem traversal, exposing an overview of directories and files. No authentication or user interaction is required; disclosed path and filename information reveals system structure but not file contents.
