CVE-2026-94293Network attack vector

Unauthenticated AAS data manipulation via unguarded REST API

Published Oct 6, 2026 · Updated Oct 6, 2026

Missing authentication in Murrelektronik AAS Edge Client allows remote attackers to read and alter AAS submodel data through its REST API. The API listens on all interfaces at TCP port 18000, omits authentication for GET and PATCH endpoints, and accepts requests from any origin. Network reachability suffices; altered data is stored locally and forwarded to the configured central AAS server, while a malicious web page can also reach the API from a user's network.
