CVE-2018-1002102 (GCVE-0-2018-1002102)

Vulnerability from cvelistv5

Published

Modified

2024-09-17 00:56

Severity ?

2.6 (Low) - CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:L/I:N/A:N

CWE

CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')

Summary

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.
