TITLE

IP-in-IP protocol routes arbitrary traffic by default

Trust: 0.8

sources: CERT/CC: VU#636397

DESCRIPTION

IP-in-IP protocol specifies IP Encapsulation within IP standard (RFC 2003, STD 1) that decapsulate and route IP-in-IP traffic is vulnerable to spoofing, access-control bypass and other unexpected behavior due to the lack of validation to verify network packets before decapsulation and routing. IP-in-IP encapsulation is a tunneling protocol specified in RFC 2003 that allows for IP packets to be encapsulated inside another IP packets. This is very similar to IPSEC VPNs in tunnel mode, except in the case of IP-in-IP, the traffic is unencrypted. An IP-in-IP device is considered to be vulnerable if it accepts IP-in-IP packets from any source to any destination without explicit configuration between the specified source and destination IP addresses. This unexpected Data Processing Error (CWE-19) by a vulnerable device can be abused to perform reflective DDoS and in certain scenarios used to bypass network access control lists. Because the forwarded network packet may not be inspected or verified by vulnerable devices, there are possibly other unexpected behaviors that can be abused by an attacker on the target device or the target device's network environment. An unauthenticated attacker can route network traffic through a vulnerable device, which may lead to reflective DDoS, information leak and bypass of network access controls. Cisco NX-OS Software is a data center-level operating system software used by a set of switches of Cisco. A code issue vulnerability exists in Cisco NX-OS Software due to the program decapsulating and processing the IP in an IP packet destined for a locally configured IP address. A remote attacker can exploit this vulnerability to bypass the access control list or cause a denial of service by means of a specially crafted IP in the IP packet. The following products and versions are affected: Nexus 1000 Virtual Edge for VMware vSphere; Nexus 1000V Switch for Microsoft Hyper-V; Nexus 1000V Switch for VMware vSphere; Nexus 3000 Series Switches; Nexus 5500 Platform Switches; Nexus 5600 Platform Switches; Nexus 6000 Switches ; Nexus 7000 Series Switches; Nexus 9000 Series Switches in standalone NX-OS mode; UCS 6200 Series Fabric Interconnects; UCS 6300 Series Fabric Interconnects
