Code Snippet Example

A potential code snippet exploiting this vulnerability could use the vulnerable API in a web service as follows:

@WebService
public class VulnerableWebService {
  public void vulnerableMethod(String data) {
    // Exploitable code using the vulnerable API
    Hotspot apiInstance = new Hotspot();
    apiInstance.updateData(data);
  }
}
