How the Exploit Works
The CVE-2025-47532 vulnerability exploits the deserialization process in the CoinPayments.net Payment Gateway for WooCommerce. Deserialization is the process of converting data from a format suitable for storage or transmission back into an object. When this process does not properly verify or sanitize the data, it can be exploited by an attacker to inject malicious objects, leading to what’s known as an Object Injection vulnerability. In this case, a successful exploit could result in a range of impacts, from unauthorized access to sensitive data to a complete system compromise.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. The attacker sends a POST request to the payment gateway with a malicious payload that exploits the deserialization vulnerability:
POST /payment_gateway/process HTTP/1.1
Host: targetstore.com
Content-Type: application/json
{ "malicious_payload": "..." }In this payload, the attacker would include malicious code crafted to exploit the insecure deserialization. When processed by the server, this could allow the attacker to execute arbitrary code, leading to potential system compromise or data leakage.
Recommended Mitigation Measures
Users of the affected versions of CoinPayments.net Payment Gateway for WooCommerce are strongly advised to apply the vendor patch as soon as possible. In the interim, or if applying the patch is not immediately feasible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary mitigation against potential attacks. However, these should not be considered long-term solutions, as they do not address the underlying vulnerability.
