identify the dns vulnerability where a resolver receives a bogus response to a dns query. all subsequent queries receive the wrong information and redirect connections to the wrong ip address.
The DNS vulnerability you are referring to is commonly known as a DNS cache poisoning attack or DNS spoofing. In this type of attack, an attacker tricks a DNS resolver into storing and serving incorrect DNS information.
Here's how the attack typically works:
The attacker sends a forged DNS response packet to a DNS resolver. The forged response contains false information, such as incorrect IP addresses associated with domain names.
The DNS resolver receives the forged response and stores it in its cache, associating the incorrect IP addresses with the corresponding domain names.
Subsequent DNS queries made by clients that rely on the compromised DNS resolver will receive the incorrect information from the cache. This can lead to connections being redirected to the wrong IP addresses, potentially allowing the attacker to intercept or manipulate network traffic.
DNS cache poisoning attacks can have severe consequences, as they can be used to redirect users to malicious websites, intercept sensitive information, or disrupt network communication.
To mitigate the risk of DNS cache poisoning, it is important to implement security measures such as using DNSSEC (Domain Name System Security Extensions), which adds digital signatures to DNS records to ensure their authenticity. Additionally, DNS resolvers should be properly configured to minimize the risk of cache poisoning and regularly update their software to patch any known vulnerabilities.
