CVE-2023-25131Network attack vector

Administrative access via unchanged default credentials

Published Apr 24, 2023 · Updated Feb 4, 2025

Use of default passwords in CyberPower PowerPanel Business 4.8.6 and earlier allows remote attackers to gain administrative access. The Local/Remote and Management web interfaces initialize the admin account with the password admin and do not require a change during installation or first login. Network access to the configured web service is sufficient; successful login exposes administrative functions, including power-device commands and host shutdown or reboot controls.
