ISC BIND < 8.4.7-P1 Outgoing Query Predictable DNS Query ID (deprecated)

medium Nessus Network Monitor Plugin ID 4195


The remote DNS server is vulnerable to a cache-poisoning attack.


The remote host is running a version of BIND DNS Server prior to 8.4.7-P1. This version of BIND is vulnerable to a flaw that would allow cache poisoning. An attacker exploiting this flaw would need to be able to manipulate the vulnerable DNS server into contacting a malicious DNS server. Successful exploitation would lead to a cache-poisoning attack.


BIND 8 is no longer supported by ISC. Upgrade or patch according to vendor recommendations.
