BIND 9 | 9.18.11-S1 to 9.18.37-S1
BIND 9 | 9.20.9-S1 to 9.20.10-S1

How the Exploit Works

This exploit works by sending malicious requests to a vulnerable caching resolver that has been configured to use EDNS Client Subnet (ECS) options. This, in turn, manipulates the caching mechanism of the resolver leading to incorrect data being stored and served to the clients. This form of attack is commonly known as a cache-poisoning attack, which can result in system compromise or data leakage.

Conceptual Example Code

Below is a conceptual example of a malicious DNS request that could exploit this vulnerability:

GET /dns-query?dns=AAABAAABAAAAAAAAA3d3dwdleGFtcGxlA2NvbQAAAQAB HTTP/1.1
Host: vulnerable-dns-resolver.example.com
Accept: application/dns-message
X-Forwarded-For: malicious-ip-address

In this example, the attacker sends a GET request with a DNS query. The `X-Forwarded-For` header is used to spoof the client’s IP address, tricking the DNS resolver into thinking the request is coming from a different source. This could lead to the cache poisoning, as the resolver might end up storing and serving incorrect data.
To mitigate the risk of this vulnerability, it is recommended to apply the vendor-supplied patch or use WAF/IDS as a temporary mitigation strategy. Regular patch management and monitoring of network activity can also help in identifying any unusual patterns that may signify an attack.
