CVE-2025-7044

An Improper Input Validation vulnerability exists in the user websocket handler of MAAS. An authenticated, unprivileged attacker can intercept a user.update websocket request and inject the is_superuser property set to true. The server improperly validates this input, allowing the attacker to self-promote to an administrator role. This results in full administrative control over the MAAS deployment.

Summary		(es) Una vulnerabilidad de validación de entrada incorrecta existe en el manejador de websockets de usuario de MAAS. Un atacante autenticado y sin privilegios puede interceptar una solicitud websocket user.update e inyectar la propiedad is_superuser establecida en verdadero. El servidor valida incorrectamente esta entrada, permitiendo al atacante autopromoverse a un rol de administrador. Esto resulta en control administrativo total sobre el despliegue de MAAS.
