In the Tailscale Windows client, the local API was bound to a local TCP socket, and communicated with the Windows client GUI in cleartext with no Host header verification. This allowed an attacker-controlled website visited by the node to rebind DNS to an attacker-controlled DNS server, and then make local API requests in the client, including changing the coordination server to an attacker-controlled coordination server. An attacker-controlled coordination server can send malicious URL responses to the client, including pushing executables or installing an SMB share. These allow the attacker to remotely execute code on the node. All Windows clients prior to version v.1.32.3 are affected. If you are running Tailscale on Windows, upgrade to v1.32.3 or later to remediate the issue."}, {"lang": "es", "value": "Una vulnerabilidad identificada en el cliente Tailscale de Windows permite que un sitio web malicioso reconfigure el daemon Tailscale \"tailscaled\", que luego puede usarse para ejecutar c\u00f3digo de forma remota. En el cliente Tailscale de Windows, la API local estaba vinculada a un socket TCP local y se comunicaba con la GUI del cliente de Windows en texto plano sin verificaci\u00f3n del encabezado del Host. Esto permiti\u00f3 que un sitio web controlado por un atacante visitado por el nodo volviera a vincular DNS a un servidor DNS controlado por un atacante y luego realizar solicitudes de API locales en el cliente, incluido el cambio del servidor de coordinaci\u00f3n a un servidor de coordinaci\u00f3n controlado por un atacante. Un servidor de coordinaci\u00f3n controlado por un atacante puede enviar respuestas URL maliciosas al cliente, incluida la inserci\u00f3n de ejecutables o la instalaci\u00f3n de un recurso compartido SMB. Estos permiten al atacante ejecutar c\u00f3digo de forma remota en el nodo. Todos los clientes de Windows anteriores a la versi\u00f3n v.1.32.3 se ven afectados.
