Song Song10 proposed very recently a password-based authentication and key establishment protocol using smart cards which attempts to solve some weaknesses found in a previous scheme suggested by Xu, Zhu, and Feng XZF09. In this paper, we present attacks on the improved protocol, showing that it fails to achieve the claimed security goals.
