Unsecured Tunneling Protocols Expose 4.2 Million Hosts, Including VPNs and Routers

New research has uncovered security vulnerabilities in multiple tunneling protocols that could allow attackers to perform a wide range of attacks. "Internet hosts that accept tunneling packets without verifying the sender's identity can be hijacked to perform anonymous attacks and provide access ...

The vulnerability of packet tunneling protocols for IPv4-to-IPv6 and IPv6-to-IPv4 protocols arises from insufficient checks on the source of the communication channel. This allows attackers to execute attacks such as “spoofing of trusted objects”.

The vulnerability of IPv4-to-Ipv6 and IPv6-to-Ipv4 tunneling protocols is related to insufficient checks on the source of the communication channel. Exploiting this vulnerability allows a remote attacker to execute “host object substitution” attacks by sending a specially crafted packet with two ...
