Who should care

Administrators and users of NetMan 204 are advised to take immediate action to mitigate this vulnerability.

Technical summary

The vulnerability is caused by a lack of authentication enforcement on administrative pages and command endpoints in NetMan 204. This allows remote, unauthenticated attackers to directly request administrative pages, such as administration.html, administration-commands.html, and configuration.html, to disclose sensitive information. Attackers can also invoke privileged UPS control commands, including shutdown, reboot, switch-on-bypass, and battery test, without supplying any credentials.

Defensive priority

High

Recommended defensive actions

  • Apply patches or updates provided by the vendor to fix the vulnerability.
  • Restrict access to administrative pages and commands to authorized personnel only.
  • Monitor system logs for suspicious activity.
