Multiple Cisco Products Vulnerable to DNS Cache Poisoning Attacks

Multiple Cisco products are vulnerable to DNS cache poisoning attacks due to their use of insufficiently randomized DNS transaction IDs and UDP source ports in the DNS queries that they produce, which may allow an attacker to more easily forge DNS answers that can poison DNS caches. To exploit th...
