CVE-2026-81573Network attack vector

WebAdmin takeover via unrestricted remote configuration commands

Published Aug 27, 2026 · Updated Aug 27, 2026

Improper access control in WIBU-SYSTEMS AG CodeMeter Runtime before 8.41a or 9.10 allows remote attackers to take over WebAdmin. The configuration command handler fails to verify network origin before executing commands reserved for local or same-network clients, exposing configuration reads and selected Server.ini writes. Server mode is required; unauthenticated remote peers can obtain the WebAdmin credential hash, overwrite selected settings, and assume WebAdmin control.
