A vulnerability in the IPsec component of StarOS for Cisco ASR 5000 Series routers could allow an unauthenticated, remote attacker to terminate all active IPsec VPN tunnels and prevent new tunnels from establishing, resulting in a denial of service (DoS) condition. This vulnerability affects the following Cisco products: Cisco ASR 5000/5500 Series routers, Cisco Virtualized Packet Core (VPC). More Information: CSCva13631.

The SSH implementation in Cisco StarOS before 19.3.M0.62771 and 20.x before 20.0.M0.62768 on ASR 5000 devices mishandles a multi-user public-key authentication configuration, which allows remote authenticated users to gain privileges by establishing a connection from an endpoint that was previously used for an administrator's connection, aka Bug ID CSCux22492. La implementación de SSH en Cisco StarOS en versiones anteriores a 19.3.M0.62771 y 20.x en versiones anteriores a 20.0.M0.62768 en dispositivos ASR 5000 no maneja correctamente una configuración de autenticación de clave pública multi usuario, lo que permite a usuarios remotos autenticados obtener privilegios estableciendo una conexión desde un dispositivo final que fue previamente utilizado para la conexión de un administrador, también conocida como Bug ID CSCux22492. • http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160218-asr http://www.securitytracker.com/id/1035062 • CWE-264: Permissions, Privileges, and Access Controls •
