CVE-2022-36560Network attack vector

Root access via exposed hard-coded passcodes

Published Aug 29, 2022 · Updated Aug 3, 2024

Hard-coded credentials in Seiko SkyBridge MB-A200 01.00.04 and earlier allow remote attackers to obtain root access. The firmware embeds reusable root passcodes in /etc/srapi/config/system.conf and /usr/sbin/ssol-sshd.sh instead of generating device-specific secrets. Network access to the device is the gate; successful use authenticates as root, exposing all privileges available to that account.
