{"id":"UBUNTU-CVE-2018-1002102","details":"Improper validation of URL redirection in the Kubernetes API server in versions prior to v1.14.0 allows an attacker-controlled Kubelet to redirect API server requests from streaming endpoints to arbitrary hosts. Impacted API servers will follow the redirect as a GET request with client-certificate credentials for authenticating to the Kubelet.","modified":"2025-07-14T06:59:56.391229Z","published":"2019-12-05T16:15:00Z","withdrawn":"2025-08-28T16:59:01Z","upstream":["CVE-2018-1002102"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-1002102"},{"type":"REPORT","url":"https://github.com/kubernetes/kubernetes/issues/85867"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-1002102"}],"affected":[{"package":{"name":"kubernetes","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/kubernetes@1.0?arch=source&distro=esm-apps/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-1002102.json"}},{"package":{"name":"kubernetes","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/kubernetes@1.0?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-1002102.json"}},{"package":{"name":"kubernetes","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/kubernetes@1.0?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-1002102.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:L/I:N/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:L/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
