Summary
A vulnerability was identified in seeedstudio ReSpeaker LinkIt7688. Impacted is an unknown function of the file /etc/shadow of the component Administrative Interface. The manipulation leads to use of default credentials. An attack has to be approached locally. A high degree of complexity is needed for the attack. The exploitability is considered difficult. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
