CVE-2023-28452

Name of the Vulnerable Software and Affected Versions CoreDNS versions through 1.10.1

Description An issue was discovered in DNS resolving software, which triggers a resolver to ignore valid responses, thus causing denial of service for normal resolution. In an exploit, the attacker could forge a response targeting the source port of a vulnerable resolver without the need to guess the correct TXID.

Recommendations For CoreDNS versions through 1.10.1, update to a version later than 1.10.1 to resolve the issue. At the moment, there is no information about additional mitigation measures for this vulnerability.
