26

FAUCET Score

CVE-2019-11243 is a high-severity vulnerability affecting Kubernetes versions 1.12.0-1.12.4 and 1.13.0, as well as related NetApp products. It stems from an incomplete credential removal process within the rest.AnonymousClientConfig() method, specifically failing to clear service account credentials loaded via rest.InClusterConfig(). With a CVSS score of 8.1, this vulnerability presents a high risk due to its network-based attack vector, low attack complexity, and potential for complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, the flaw's nature warrants prompt patching to mitigate potential unauthorized access.
