Morty writes "DNS rebinding attacks can be used by hostile websites to get browsers to attack behind firewalls, or to attack third parties. Browsers use "pinning" to prevent this, but a paper describes so-called multi-pin vulnerabilities that bypass the existing protections. Note that, from a DNS perspective, this is a "feature" rather than an implementation bug, although it's possible that DNS servers could be modified to prevent external sources from being able to point at internal resources."
