https://notcve.org/view.php?id=CVE-2017-6678
A vulnerability in the ingress UDP packet processing functionality of Cisco Virtualized Packet Core-Distributed Instance (VPC-DI) Software 19.2 through 21.0 could allow an unauthenticated, remote attacker to cause both control function (CF) instances on an affected system to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient handling of user-supplied data by the affected software. An attacker could exploit this vulnerability by sending crafted UDP packets to the distributed instance (DI) network addresses of both CF instances on an affected system. A successful exploit could allow the attacker to cause an unhandled error condition on the affected system, which would cause the CF instances to reload and consequently cause the entire VPC to reload, resulting in the disconnection of all subscribers and a DoS condition on the affected system. This vulnerability can be exploited via IPv4 traffic only. • http://www.securityfocus.com/bid/99195 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170621-vpc • CWE-399: Resource Management Errors CWE-755: Improper Handling of Exceptional Conditions •

A privilege escalation vulnerability in the Secure Shell (SSH) subsystem in the StarOS operating system for Cisco ASR 5000 Series, ASR 5500 Series, ASR 5700 Series devices, and Cisco Virtualized Packet Core could allow an authenticated, remote attacker to gain unrestricted, root shell access. The vulnerability is due to missing input validation of parameters passed during SSH or SFTP login. An attacker could exploit this vulnerability by providing crafted user input to the SSH or SFTP command-line interface (CLI) during SSH or SFTP login. An exploit could allow an authenticated attacker to gain root privileges access on the router. Note: Only traffic directed to the affected system can be used to exploit this vulnerability. • http://www.securityfocus.com/bid/96913 http://www.securitytracker.com/id/1038050 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170315-asr • CWE-264: Permissions, Privileges, and Access Controls CWE-306: Missing Authentication for Critical Function •
