CVE-2023-23578Network attack vector

Unauthenticated command access via exposed ADB port

Published May 10, 2023 · Updated Jan 28, 2025

Improper access control in SkyBridge MB-A200 firmware 01.00.05 and earlier allows remote attackers to connect to the router's ADB port. The firmware exposes the Android Debug Bridge service when the appliance starts without enforcing authentication before accepting a connection. Network reachability to the ADB port is required; successful access permits built-in command execution and can expose or alter device data or disrupt operation.
