CVE-2021-32504Network attack vector

Information disclosure via unrestricted sensitive web URLs

Published Jul 19, 2022 · Updated Aug 3, 2024

Missing authorization in SICK AG FTMg firmware before 2.8 allows remote attackers to read sensitive data through crafted HTTP GET requests. The embedded web server serves sensitive URLs without enforcing the maintenance-level authorization intended for those resources. No authentication or user interaction is required, but SICK has not disclosed the affected paths or specific data returned; the confirmed impact is limited to information disclosure that can assist further attacks.
