Detailsinfo

A vulnerability classified as critical was found in Kubernetes up to 1.13.x (Virtualization Software). This vulnerability affects an unknown code of the component API Server. The manipulation with an unknown input leads to a redirect vulnerability. The CWE definition for the vulnerability is CWE-601. A web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a Redirect. This simplifies phishing attacks. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was published 12/05/2019 (GitHub Repository). The advisory is available at github.com. This vulnerability was named CVE-2018-1002102 since 12/05/2018. The exploitation appears to be difficult. The attack can be initiated remotely. The exploitation requires an enhanced level of successful authentication. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1204.001 by the MITRE ATT&CK project.

Upgrading to version 1.14.0 eliminates this vulnerability.

Once again VulDB remains the best source for vulnerability data.
