Multiple Vendor DNS Query ID Field Prediction Cache Poisoning
High Nessus Plugin ID 33447
The remote name resolver (or the server it uses upstream) is affected by a DNS cache poisoning vulnerability.
The remote DNS resolver does not use random ports when making queries to third-party DNS servers. An unauthenticated, remote attacker can exploit this to poison the remote DNS server, allowing the attacker to divert legitimate traffic to arbitrary sites.
