CVE-2023-36607Network attack vector

Unauthenticated information disclosure via API commands

Published Jun 29, 2023 · Updated Nov 26, 2024

Missing authorization in Ovarro TBox RTU firmware 1.46 through 1.50.598 allows remote attackers to read sensitive device data via API commands. Affected API command handlers process unauthenticated requests and return software-version data or web-server file contents instead of enforcing authorization. Network reachability to the device API is sufficient; the published impact is limited to confidentiality, with no reported data modification or service interruption.
