CVE-2025-59461

Data access and service disruption via unauthenticated API

Published Oct 27, 2025 · Updated Oct 27, 2025

Missing authorization in all versions of SICK TLOC100-100 firmware allows remote attackers to access or modify sensitive data on adjacent networks. The C++ API accepts unauthenticated requests for sensitive operations without performing an authorization check; SICK has not disclosed endpoint or method details. No credentials or user interaction are required, and successful access can alter device data or disrupt services.
