A vulnerability, which was classified as problematic, was found in Kubernetes up to 1.0-1.12/1.13.11/1.14.7/1.15.4/1.16.1 (Virtualization Software). Affected is an unknown function of the component API Server. The manipulation as part of a JSON Payload leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. This is going to have an impact on availability. CVE summarizes:
Improper input validation in the Kubernetes API server in versions v1.0-1.12 and versions prior to v1.13.12, v1.14.8, v1.15.5, and v1.16.2 allows authorized users to send malicious YAML or JSON payloads, causing the API server to consume excessive CPU or memory, potentially crashing and becoming unavailable. Prior to v1.14.0, default RBAC policy authorized anonymous users to submit requests that could trigger this vulnerability. Clusters upgraded from a version prior to v1.14.0 keep the more permissive policy by default for backwards compatibility.
The weakness was published 10/17/2019 (Website). The advisory is available at groups.google.com. This vulnerability is traded as CVE-2019-11253 since 04/17/2019. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available.
Upgrading to version 1.13.12, 1.14.8, 1.15.5 or 1.16.2 eliminates this vulnerability.
