CVE-2023-31410Network attack vector

Traffic disclosure and manipulation via missing TLS

Published Jun 19, 2023 · Updated Jun 1, 2026

Cleartext transmission in SICK AG EventCam App all versions allows remote attackers to read or alter client traffic over Ethernet. The app-to-client communication channel omits TLS, exposing sensitive data in transit to interception and modification. Exploitation requires access to the Ethernet path between the app and its client, enabling eavesdropping and in-transit data manipulation.
