Workaround
As a temporary workaround, administrators can implement input validation and sanitization measures on the affected input field. This can help mitigate the risk of XSS attacks until the EC-CUBE installation is updated to a secure version. Here is an example of input validation using PHP:
$input = $_POST['input_field'];
// Sanitize the input
$sanitized_input = htmlspecialchars($input);
// Validate the input
if ($sanitized_input !== $input) {
// Handle the validation error
}
Conclusion
The EC-CUBE Cross-site scripting vulnerability (CVE-2021-20717) poses a moderate security risk to EC-CUBE installations. To mitigate this vulnerability, it is recommended to update EC-CUBE to version 4.0.6 or later. Administrators can also implement input validation and sanitization measures as a temporary workaround.
