How the Exploit Works
The exploit leverages the deserialization of untrusted data vulnerability in the Rapyd Payment Extension for WooCommerce. Deserialization is the process of converting data from a flat file or a database into an object in an object-oriented programming language. This vulnerability arises when an attacker can manipulate the serialized (flattened) data to include malicious code, which is then executed when the data is deserialized (converted back into an object). In this case, the attacker can perform an Object Injection, essentially injecting malicious objects into the serialized data stream, leading to potential system compromise or data leakage.
Conceptual Example Code
Here’s a conceptual example of a malicious HTTP request that could exploit this vulnerability:
POST /payment/process HTTP/1.1
Host: affected-woocommerce-site.com
Content-Type: application/json
{
"paymentData": "eyJvYmplY3RJZCI6IjEiLCJjbGFzcyI6Im1hbGljaW91cy1jbGFzcyIsIm1ldGhvZCI6Im1hbGljaW91cy1tZXRob2QifQ=="
}In this example, the `paymentData` field contains a base64 encoded serialized object. If the object is maliciously crafted and the application doesn’t properly validate or sanitize the input, it could lead to remote code execution or data leakage when the object is deserialized.
Please note this example is conceptual and oversimplified for illustrative purposes. Actual exploitation of the vulnerability would likely involve complex manipulation of serialized objects and depend on specific application details.
Recommendations for Mitigation
The primary mitigation guidance for CVE-2025-30618 is to apply the vendor patch. For immediate protection, it is recommended to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation. As a best practice, it is also crucial to ensure that all software components are regularly updated, and rigorous input validation and sanitization measures are in place.
