Nuclio vulnerabilities

Nuclio, a serverless framework, prior to version 1.17.4 has an incomplete fix for unauthenticated OS command injection in the dashboard on the local/Docker platform. The list-all resource path interpolates the resourceNamespace parameter unquoted into a /bin/sh -c command string, allowing an unauthenticated attacker to inject shell metacharacters via HTTP headers and execute arbitrary commands inside the dashboard container.

Nuclio, a serverless framework, prior to version 1.17.4 has an OS command injection vulnerability in the local Docker platform. The function namespace is interpolated unvalidated into a double-quoted docker ps --filter command executed via /bin/sh -c. Because the default auth kind is nop (unauthenticated), a remote attacker can inject arbitrary OS commands that run as root inside the dashboard container, which holds the Docker socket, leading to host compromise.

Nuclio, a serverless framework, from version 1.6.19 to before 1.17.2 has a vulnerability in the Dashboard build pipeline that 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 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.

Nuclio, a serverless framework, prior to version 1.16.5 has a vulnerability in the Java runtime that generates a build.gradle file during function builds using Go's text/template package. The template renders runtimeAttributes.repositories[] values with the {{ . }} action, which performs no escaping. An attacker can embed a closing brace to break out of the repositories block and append arbitrary Groovy statements that execute unconditionally during the Gradle configuration phase.

Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.16.5, Nuclio Dashboard exposes POST /api/functions without authentication by default (NOP auth mode). The spec.handler field (e.g., mymodule:myfunction) is parsed by functionconfig.ParseHandler() which splits on : only — no path validation is applied to the module portion. This issue has been patched in version 1.16.5.

Nuclio before version 1.16.4 contains a command injection vulnerability in the construction of the curl invocation for cron triggers. The event.headers keys and event.body are not properly sanitized, allowing injection of dangerous arguments into the command executed in the CronJob container.

Nuclio before version 1.16.0 contains a vulnerability in the project management API of Nuclio Dashboard. Any authenticated user, even without membership in the target project, can bypass OPA authorization checks on write paths (PUT /api/projects/{id}, DELETE /api/projects) and modify or delete any project along with all its associated resources.
