IBM Robotic Process Automation (RPA) is a widely used solution for automating repetitive, rule-based tasks by mimicking human actions. Recently, a security vulnerability has been discovered in IBM RPA versions 21.. through 21..7.latest, which allows unauthorized access to data due to insufficient authorization validation on some API routes. This vulnerability has been assigned the identifier CVE-2023-23476 and has an IBM X-Force ID of 245425.

In this post, we will discuss the details of this security vulnerability, provide code snippets as examples, and offer links to original references. We will also provide an overview of the exploit to give you a better understanding of its potential risks.

Security Vulnerability Details

IBM RPA 21.. to 21..7.latest is affected by a vulnerability that enables an attacker to gain unauthorized access to sensitive data by exploiting the insufficient authorization validation on certain API routes. This vulnerability can grant unauthorized users access to critical data and potentially manipulate that information for malicious purposes. It highlights the importance of strict authorization validation checks on API routes to prevent such security breaches.

Code Snippet Example

Below is a sample code snippet that demonstrates the lack of proper authorization validation in an API route. In this example, the "RestrictedDataAPI" should be limited to authorized users, but the code does not implement the necessary validation checks.

const express = require('express');
const router = express.Router();

// Vulnerable API Route: Insufficient authorization validation
router.get('/RestrictedDataAPI', (req, res) => {
  const data = getRestrictedDataFromDatabase();
  res.json(data);
});

module.exports = router;

To mitigate this vulnerability, proper authorization validation should be implemented, as shown in the code snippet below:

const express = require('express');
const router = express.Router();

// Secure API Route: Proper authorization validation
router.get('/RestrictedDataAPI', (req, res) => {
  if (isUserAuthorized(req.user)) {
    const data = getRestrictedDataFromDatabase();
    res.json(data);
  } else {
    res.status(403).json({ message: 'Unauthorized access' });
  }
});

module.exports = router;
