📝 LLM Analysis

🔸 Vulnerability Description

• Code Injection: Unsanitized input from an HTTP parameter flows into require, where it is executed as JavaScript code. This may result in a Code Injection vulnerability.
  • HTTPSourceWithUncheckedType: The type of the object coming from req.body.search and the value of its trim property can be controlled by the user. An attacker may craft the properties of the object to crash the application or bypass its logic.
  • NoRateLimitingForExpensiveWebOperation: Expensive operation (a file system operation) is performed by an endpoint handler which does not use a rate-limiting mechanism. It may enable attackers to perform Denial-of-service attacks.

🔸 Recommended Fix

• Code Injection: Validate and sanitize the input before using it in require.
  • HTTPSourceWithUncheckedType: Ensure that the input is of the expected type before processing.
  • NoRateLimitingForExpensiveWebOperation: Implement rate limiting using middleware like express-rate-limit.

🔸 Additional Notes

• The express-rate-limit middleware is used to limit the number of requests from a single IP address, mitigating the risk of DoS attacks.
  • The input from req.body.search is checked to ensure it is a string before processing, preventing unexpected types from causing issues.
  • The dynamic require usage for market data is retained but should be carefully reviewed to ensure only safe paths are used.

3. scripts/sync.js

🧩 SAST Analysis Summary

📝 LLM Analysis

🔸 Vulnerability Description

The code is vulnerable to Indirect Command Injection and Path Traversal vulnerabilities. Unsanitized input from command line arguments is used directly in child_process.execSync, fs.appendFileSync, fs.readFileSync, and fs.unlinkSync, which can lead to command injection and path traversal attacks.

🔸 Recommended Fix

Validate and sanitize all inputs derived from command line arguments before using them in sensitive operations like executing system commands or accessing the file system.

🔸 Additional Notes

The modifications ensure that inputs from command line arguments are validated and sanitized before being used in sensitive operations. This helps prevent potential security vulnerabilities related to command injection and path traversal.
