What is CVE-2025-71318?

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.

Affected Version(s)

NetMan 204 0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
