Automated description summarized from trusted sources.

CVE-2025-10127 is a vulnerability affecting Daikin Security Gateway devices. It stems from a weak password recovery mechanism, specifically an authorization bypass through a user-controlled key vulnerability. This allows unauthorized attackers to bypass authentication and gain access to the system without any credentials. The vulnerability lies in a password-reset endpoint that trusts attacker-controlled input. By sending a crafted POST request, an attacker can trigger the gateway to reset its administrative account(s) to default credentials. Once reset, the attacker can authenticate, access the web UI/API, change settings, create persistent accounts or backdoors, and control functions exposed by the gateway, including cloud connectivity.

Description: Daikin Security Gateway is vulnerable to an authorization bypass through a user-controlled key vulnerability that could allow an attacker to bypass authentication. An unauthorized attacker could access the system without prior credentials.
