CVE-2018-1002100

MEDIUM
4.2NVD

Summary

generated automatically from NVD data

Kubernetes versions 1.5.x through 1.8.x, and 1.9.x before 1.9.6, contain an input validation flaw (CWE-20) in the kubectl cp command. It handles tar data returned from a container insecurely, so a malicious container could cause arbitrary files on the local machine running kubectl to be overwritten. The issue is rated MEDIUM with a CVSS v3.0 score of 4.2, driven by high impact on integrity.

NVD description

In Kubernetes versions 1.5.x, 1.6.x, 1.7.x, 1.8.x, and prior to version 1.9.6, the kubectl cp command insecurely handles tar data returned from the container, and can be caused to overwrite arbitrary local files.
