# Inclusion of Functionality from Untrusted Control Sphere (CWE-829)

The product imports, requires, or includes executable functionality from a source that is outside of the intended control sphere.

**Stack:** JavaScript

- Prevalence: उच्च बार-बार शोषित
- Impact: उच्च 3 उच्च गंभीरता वाले नियम
- Prevention: प्रलेखित 4 फिक्स उदाहरण

**OWASP:** Vulnerable and Outdated Components (A06:2021-Vulnerable and Outdated Components) - #6

## Description

When software includes functionality from untrusted sources (such as third-party scripts, external modules, or code from untrusted URLs), attackers can inject malicious code that will be executed with the same privileges as the application.

## Prevention

1 Shoulder डिटेक्शन नियमों पर आधारित Inclusion of Untrusted Functionality के लिए रोकथाम रणनीतियाँ।

### JavaScript

Use allowlists for permitted models and verify integrity with checksums

## Warning Signs

- [HIGH] Potential supply chain vulnerability: ...
- [HIGH] potential supply chain vulnerabilities in AI/LLM implementations

## Consequences

- अनधिकृत कोड निष्पादित करना
- एप्लिकेशन डेटा पढ़ना
- एप्लिकेशन डेटा संशोधित करना

## Mitigations

- केवल विश्वसनीय, सत्यापित स्रोतों से कोड शामिल करें
- बाहरी स्क्रिप्ट्स के लिए Subresource Integrity (SRI) का उपयोग करें
- निष्पादन योग्य कोड के स्रोतों को सीमित करने के लिए Content Security Policy (CSP) लागू करें

## Detection

- Total rules: 4
- Languages: go, javascript, typescript, yaml, python

## Rules by Language

### Javascript (1 rules)

- **LLM Supply Chain Vulnerabilities** [HIGH]: Detects potential supply chain vulnerabilities in AI/LLM implementations.
OWASP LLM05 - Supply Chain Vulnerabilities.

Supply chain attacks in AI can occur through:
- Loading models from untrusted sources
- Using unverified model weights or configurations
- Third-party plugins/tools without integrity verification
- Compromised training data sources
- Insecure model serialization formats

This rule detects:
- Dynamic model loading from user input
- Models loaded from HTTP (not HTTPS)
- Missing in
  - Remediation: Use allowlists for permitted models and verify integrity with checksums.

```javascript
if (!ALLOWED_MODELS[modelId]) {
  throw new Error('Model not in allowlist');
}
const model = await loadVerifiedModel(modelId);
```
