Best 7 Steps to Prevent Remote Code Execution RCE in TypeScript ERP

Remote Code Execution (RCE) is a critical security vulnerability allowing attackers to execute arbitrary code on a server. In TypeScript-based ERP systems, this vulnerability can lead to severe data breaches, financial loss, and reputation damage. This blog post explains RCE in TypeScript-based ERP systems, its implications, and how to secure your system with actionable steps and coding examples.

What is Remote Code Execution (RCE)?

Remote Code Execution is a vulnerability where attackers exploit system weaknesses to execute unauthorized commands. These vulnerabilities often stem from improper input validation, insecure configurations, or dependencies with known flaws. For TypeScript-based ERP systems, understanding how RCE works is vital to ensuring a secure architecture.

Common Causes of Remote Code Execution RCE in TypeScript-Based ERP Systems

1. Unvalidated User Inputs: Not sanitizing inputs before processing.
2. Improper Use of Dynamic Functions: For example, using eval in TypeScript.
3. Insecure Dependencies: Using outdated libraries.
4. Misconfigured Servers: Poor server-side settings leading to exploitation.

Step 1: Use Strong Input Validation

Input validation is your first line of defense. Below is an example of secure input validation in TypeScript:

function validateInput(input: string): string {
    const regex = /^[a-zA-Z0-9-_]+$/;
    if (!regex.test(input)) {
        throw new Error("Invalid input detected!");
    }
    return input;
}
try {
    const userInput = validateInput("test-input");
    console.log(`Validated Input: ${userInput}`);
} catch (error) {
    console.error(error.message);
}

By validating inputs, you can mitigate the risk of malicious payloads entering your system.

Step 2: Avoid Using eval and Similar Functions

Dynamic evaluation functions like eval should be avoided. Here’s why:

Bad Practice:

const userCode = "console.log('Hello, world!')";
eval(userCode); // Unsafe, vulnerable to RCE

Secure Alternative:

const userCode = "console.log('Hello, world!')";
// Process using safe and predefined logic
console.log(`Executing code: ${userCode}`);

---

Step 3: Secure Dependency Management

Regularly audit dependencies in your TypeScript ERP system. Use tools like npm audit:

npm audit
npm audit fix

For example, ensure all libraries are updated:

"dependencies": {
    "express": "^4.18.3", 
    "typescript": "^4.9.4"
}

---

Step 4: Implement Secure Configuration Practices

Ensure your ERP servers are configured securely:

• Disable unused endpoints.
• Limit privileges for user roles.
• Configure Content Security Policies (CSP).
