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

Vulnerability from cvelistv5 – Published: 2019-12-05 16:05 – Updated: 2024-09-17 00:56

Title

Kubernetes API server follows unvalidated redirects from streaming Kubelet endpoints

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.

Severity

2.6 (Low)
