What is CVE-2026-25715?

The web management interface of certain devices allows administrators to set both the username and password to empty values. This severe flaw permits authentication with these blank credentials, effectively bypassing authentication requirements across critical management channels. As a result, any network-adjacent attacker can gain full administrative access to the device without any valid authentication, posing significant security risks.
