A vulnerability in the reassembly logic for fragmented IPv4 packets of Cisco StarOS running on virtual platforms could allow an unauthenticated, remote attacker to trigger a reload of the npusim process, resulting in a denial of service (DoS) condition. There are four instances of the npusim process running per Service Function (SF) instance, each handling a subset of all traffic flowing across the device. It is possible to trigger a reload of all four instances of the npusim process around the same time. The vulnerability is due to improper handling of fragmented IPv4 packets containing options. An attacker could exploit this vulnerability by sending a malicious IPv4 packet across an affected device. • http://www.securityfocus.com/bid/104723 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180711-staros-dos • CWE-20: Improper Input Validation •

A vulnerability in the IPsec Manager of Cisco StarOS for Cisco Aggregation Services Router (ASR) 5000 Series Routers and Virtualized Packet Core (VPC) System Software could allow an unauthenticated, remote attacker to terminate all active IPsec VPN tunnels and prevent new tunnels from being established, resulting in a denial of service (DoS) condition. The vulnerability is due to improper processing of corrupted Internet Key Exchange Version 2 (IKEv2) messages. An attacker could exploit this vulnerability by sending crafted IKEv2 messages toward an affected router. A successful exploit could allow the attacker to cause the ipsecmgr service to reload. A reload of this service could cause all IPsec VPN tunnels to be terminated and prevent new tunnels from being established until the service has restarted, resulting in a DoS condition. • http://www.securityfocus.com/bid/103935 http://www.securitytracker.com/id/1040721 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-starosasr • CWE-399: Resource Management Errors •

A vulnerability in the CLI of the Cisco StarOS operating system for Cisco ASR 5000 Series Aggregation Services Routers could allow an authenticated, local attacker to perform a command injection attack on an affected system. The vulnerability is due to insufficient validation of commands that are supplied to certain configurations in the CLI of the affected operating system. An attacker could exploit this vulnerability by injecting crafted arguments into a vulnerable CLI command for an affected system. A successful exploit could allow the attacker to insert and execute arbitrary commands in the CLI of the affected system. To exploit this vulnerability, the attacker would need to authenticate to an affected system by using valid administrator credentials. • http://www.securityfocus.com/bid/103346 http://www.securitytracker.com/id/1040466 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180307-staros • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

A vulnerability in the CLI of the Cisco StarOS operating system for Cisco ASR 5000 Series Aggregation Services Routers could allow an authenticated, local attacker to execute arbitrary commands with root privileges on an affected operating system. The vulnerability is due to insufficient validation of user-supplied input by the affected operating system. An attacker could exploit this vulnerability by authenticating to an affected system and injecting malicious arguments into a vulnerable CLI command. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the affected system.

https://notcve.org/view.php?id=CVE-2018-0117
A vulnerability in the ingress packet processing functionality of the Cisco Virtualized Packet Core-Distributed Instance (VPC-DI) Software 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 malicious traffic to the internal distributed instance (DI) network address 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 affects Cisco Virtualized Packet Core-Distributed Instance (VPC-DI) Software N4.0 through N5.5 with the Cisco StarOS operating system 19.2 through 21.3. • http://www.securityfocus.com/bid/102970 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180207-vpcdi • CWE-20: Improper Input Validation •
