'Processing a specially crafted IPv6 Type 0 Routing header can crash a device running Cisco IOS software. This vulnerability does not affect IPv6 Type 2 Routing header which is used in mobile IPv6. IPv6 is not enabled by default in Cisco IOS. Cisco has made free software available to address this vulnerability for affected customers. There are workarounds available to mitigate the effects of
Devices that are running Cisco IOS Software and configured for Mobile IP Network Address Translation (NAT) Traversal feature or Mobile IPv6 are vulnerable to a denial of service (DoS) attack that may result in a blocked interface.

IPV6 v IPV4: what are they, what's the difference, which
Autoconfiguration in IPv6 is an efficient and economic process, but has potential vulnerabilities. SLAAC (Stateless Address Autoconfiguration) is the process by which a host configures its own address based on its hardware (MAC) address. But the exposure of MAC addresses may permit host identification via interface ID, NIC vendor, or host vendor. Addresses generated by random, temporary, or
Address spoofing is a major issue on tunnels to a 6to4 relay router. For incoming traffic, the 6to4 router is unable to match the IPv4 address of the relay router with the IPv6 address of the source. Therefore, the address of the IPv6 host can easily be spoofed. The address of the 6to4 relay router can also be spoofed.
IPv6 leakage seemed to concern the researchers the most. "The vulnerability is driven by the fact that, whereas all VPN clients manipulate the IPv4 routing table, they tend to ignore the IPv6 IPv6 Vulnerabilities. IPv6 will eventually be just as popular as IPv4, if not more so. Over the next decade as IPv6 is deployed, the number of systems it is deployed on will surpass those on IPv4 Address spoofing is a major issue on tunnels to a 6to4 relay router. For incoming traffic, the 6to4 router is unable to match the IPv4 address of the relay router with the IPv6 address of the source. Therefore, the address of the IPv6 host can easily be spoofed. The address of the 6to4 relay router can also be spoofed. Educate yourself about the following vulnerabilities to safeguard your organization. Routing Header Type 0 Vulnerability. One of the IPv6 security issues involves the Routing Header Type 0 (RH0) extension header. This allows additional information to be placed behind the IP header and extends IPv6’s functionality. 12/06/2018 · Just because you're not yet using IPv6 doesn't mean you're safe from the protocol's attack vectors. Enterprise Vulnerabilities From DHS/US-CERT's National Vulnerability Database. CVE-2020 16/06/2020 · CVE-2020-11897 - CVSSv3 score: 10 - Improper handling of length parameter inconsistency in IPv6 component when handling a packet sent by an unauthorized network attacker. This vulnerability may 14/09/2016 · As your organization begins to deploy IPv6 you will need to test the IPv6 attack surface, just as you check for IPv4 security vulnerabilities. You will likely start your IPv6 deployment at the perimeter so it is those Internet-facing systems that will be first exposed. As a result, you will need to scan these systems first. You will need a vulnerability scanner that is also capable of testing
