Flux CLI Workload Injection

Flux is a tool for keeping Kubernetes clusters in sync with sources of configuration (like Git repositories), and automating updates to configuration when there is new code to deploy. Flux CLI allows users to deploy Flux components into a Kubernetes cluster via command-line. The vulnerability allows other applications to replace the Flux deployment information with arbitrary content which is deployed into the target Kubernetes cluster instead. The vulnerability is due to the improper handling of user-supplied input, which results in a path traversal that can be controlled by the attacker. Users sharing the same shell between other applications and the Flux CLI commands could be affected by this vulnerability. In some scenarios no errors may be presented, which may cause end users not to realize that something is amiss. A safe workaround is to execute Flux CLI in ephemeral and isolated shell environments, which can ensure no persistent values exist from previous processes. However, upgrading to the latest version of the CLI is still the recommended mitigation strategy.

对路径名的限制不恰当(路径遍历)

Flux2 路径遍历漏洞

Flux2是云原生计算基金会（Cloud Native Computing Foundation）的一种使 Kubernetes 集群与配置源保持同步的工具。 Flux2 v0.21.0到 v0.31.0版本存在路径遍历漏洞，该漏洞源于对用户提供的输入处理不当，攻击者利用该漏洞可以控制路径遍历。
