CVE-2025-28235Public exploitNetwork attack vector

Administrator credential disclosure via unauthenticated WebSocket messages

Published Apr 18, 2025 · Updated Apr 22, 2025

Information disclosure in Soundcraft Ui12 and Ui16 firmware 1.0.7x and 1.0.5x allows remote attackers to obtain administrator credentials. The unauthenticated /socket.io/1/websocket/ endpoint sends settings.block.pass as plaintext in WebSocket messages instead of withholding the password from unauthenticated clients. Network access to the mixer's web service is sufficient to recover the password and then authenticate to the control interface, exposing audio and configuration controls.
