Prior to 1.7.0, the DNS C2 listener accepts unauthenticated TOTP bootstrap messages and allocates server-side DNS sessions without validating OTP values, even when EnforceOTP is enabled. Because sessions are stored without a cleanup/expiry path in this flow, an unauthenticated remote actor can repeatedly create sessions and drive memory exhaustion. This vulnerability is fixed in 1.7.0."},{"lang":"es","value":"Sliver es un framework de comando y control que utiliza un netstack Wireguard personalizado. Antes de la versión 1.7.0, el oyente DNS C2 acepta mensajes de arranque TOTP no autenticados y asigna sesiones DNS del lado del servidor sin validar los valores OTP, incluso cuando EnforceOTP está habilitado. Dado que las sesiones se almacenan sin una ruta de limpieza/caducidad en este flujo, un actor remoto no autenticado puede crear sesiones repetidamente y provocar el agotamiento de la memoria.
