CVE-2023-2431

FAUCET Score

CVE-2023-2431 describes a security flaw in Kubelet that permits Kubernetes pods to bypass seccomp profile enforcement. Specifically, pods configured with a localhost seccomp profile but an empty profile field can execute in an unconfined mode, effectively disabling seccomp. This vulnerability impacts various Kubernetes distributions, including those from fedoraproject. Rated as MEDIUM severity with a CVSS score of 5.5, this vulnerability has a low attack complexity and requires local privileges to exploit. The primary impact is a high integrity loss, as it allows unauthorized actions within the affected pod, though confidentiality and availability are not directly impacted. Currently, there is no evidence of active exploitation, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, indicating a low level of public attention.
