IPv6 has three types of addressing model , namely anycast , unicast , and multicast . IPv6 does no t support broadcast address like that found in IPv4 . Table 1 below shows the specific use of IPv6 based on RFC 3513 (Network Working Group, 2003) which explains the IPv6 addressing architecture. Table 1. Specific Use of IPv6 Study of IPv6 Sec urity Vulnerabilities. 1. Introduction to I Pv6 . IPv6, sometimes referred as next generation I P, is the new version of the IPv4 protocol that . defines numeric addresses to IPv6 Vulnerabilities (CVE) Router Advertisement Flooding Flood LAN with random RAs. DOS: •Windows 7, 2008, 2003, XP •Cisco IOS+ASA (fixed) •Juniper Netscreen •FreeBSD (should be fixed) Source: Marc Heuse Tool: flood_router6 A B C . Sniffer Detect Given the scale at which IPv6 must be deployed, it is important that the possible security implications of IPv6 are well understood and considered during the design and deployment of IPv6 networks, rather than as an afterthought. This document is organized as a list of frequently asked questions about IPv6 security, providing answers and highlighting the most important aspects of IPv6 security. They can be used for IPv6 troubleshooting, intrusion detection and security audits – or for exploiting IPv6 vulnerabilities. They have been freely available on the Internet for a long time to anyone who wants them, including crackers, spammers, black hats, white hats, and national security services. Please be certain you have the appropriate rights and permissions to access any networks on

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
