Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. From version 1.6.19 to before version 1.17.2, Nuclio's Dashboard build pipeline does not sanitize the spec.build.tempDir field before using it to construct a shell command. When the Kaniko container builder is enabled, a user with function-create permission can inject shell metacharacters into this field and achieve arbitrary command execution inside the Dashboard container, which runs with a Kubernetes service account holding wildcard access to Secrets, Pods, Jobs, and Deployments in its namespace. This issue has been patched in version 1.17.2.
AnalysisAI
Shell command injection in Nuclio's Dashboard build pipeline (versions 1.6.19–1.17.1) allows an authenticated user with function-create permission to execute arbitrary commands inside the Dashboard container by embedding shell metacharacters in the spec.build.tempDir field. The post-exploitation impact is substantially amplified because the Dashboard container's Kubernetes service account holds wildcard access to Secrets, Pods, Jobs, and Deployments within its namespace, enabling full namespace-level privilege escalation from a single low-privileged API call. …
