Even though the CVE-2016-2183 has been fixed in the etcd components, to enable periodic health checks from kubelet, it was necessary to open up a new port (9979) on etcd grpc-proxy, hence this port might be considered as still vulnerable to the same type of vulnerability. The health checks on etcd grpc-proxy do not contain sensitive data (only metrics data), therefore the potential impact related to this vulnerability is minimal. The CVE-2023-0296 has been assigned to this issue to track the permanent fix in the etcd component.","state":"PUBLIC","assigner":"secalert@redhat.com","published_at":"2023-01-17 21:15:00","updated_at":"2023-02-13 04:53:00"},"problem_types":["CWE-327"],"metrics":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2023-0296","name":"https://access.redhat.com/security/cve/CVE-2023-0296","refsource":"MISC","tags":[],"title":"Red Hat Customer Portal - Access to 24x7 support and knowledge","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2161287","name":"https://bugzilla.redhat.com/show_bug.cgi?id=2161287","refsource":"MISC","tags":[],"title":"2161287 – (CVE-2023-0296) CVE-2023-0296 openshift: etcd grpc-proxy vulnerable to The Birthday attack against 64-bit block cipher","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://access.redhat.com/errata/RHSA-2023:0241","name":"https://access.redhat.com/errata/RHSA-2023:0241","refsource":"MISC","tags":[],"title":"Red Hat Customer Portal - Access to 24x7 support and knowledge","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://access.redhat.com/errata/RHSA-2022:7399","name":"https://access.redhat.com/errata/RHSA-2022:7399","refsource":"MISC","tags":[],"title":"Red Hat Customer Portal - Access to 24x7 support and knowledge","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://access.redhat.com/errata/RHSA-2023:0069","name":"https://access.redhat.com/errata/RHSA-2023:0069","refsource":"MISC","tags":[],"title":"Red Hat Customer Portal - Access to 24x7 support and knowledge","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-0296","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-0296","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2023","cve_id":"296","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"redhat","cpe5":"openshift","cpe6":"4.11","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"data_version":"4.0","data_type":"CVE","data_format":"MITRE","CVE_data_meta":{"ID":"CVE-2023-0296","ASSIGNER":"secalert@redhat.com","STATE":"PUBLIC"},"description":{"description_data":[{"lang":"eng","value":"The Birthday attack against 64-bit block ciphers flaw (CVE-2016-2183) was reported for the health checks port (9979) on etcd grpc-proxy component.
