CVE-2020-8562
2.2 · LOWOverview
CVE-2020-8562 is a low-severity vulnerability affecting kubernetes kubernetes. It was published on February 1, 2022 and has a CVSS 3.1 base score of 2.2 (LOW).
This vulnerability has a CVSS 3.1 base score of 2.2, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
As mitigations to a report from 2019 and CVE-2020-8555, Kubernetes attempts to prevent proxied connections from accessing link-local or localhost networks when making user-driven connections to Services, Pods, Nodes, or StorageClass service providers. As part of this mitigation Kubernetes does a DNS name resolution check and validates that response IPs are not in the link-local (169.254.0.0/16) or localhost (127.0.0.0/8) range. Kubernetes then performs a second DNS resolution without validation for the actual connection. If a non-standard DNS server returns different non-cached responses, a user may be able to bypass the proxy IP restriction and access private networks on the control plane.
Remediation
Check the references section for vendor advisories and patches from kubernetes. Update kubernetes to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
