What the vulnerability does

01Description

NetMan 204 fails to enforce authentication on its administrative pages and command endpoints. A remote, unauthenticated attacker can directly request administrative pages (such as administration.html, administration-commands.html, and configuration.html) to disclose sensitive information including LDAP configuration and active user details, and can invoke privileged UPS control commands — including shutdown, reboot, switch-on-bypass, and battery test — without supplying any credentials.
