Overview<\/strong><\/p>\n

The vulnerability we are discussing today, CVE-2025-4387, has been discovered in the Abandoned Cart Pro for WooCommerce plugin. Effectively, it provides a backdoor to attackers wanting to compromise a site’s server and execute potentially harmful code. Anyone using versions up to, and including, 9.16.0 of this plugin is affected by this vulnerability<\/a>.
\nGiven the popularity of WooCommerce as an ecommerce platform, this vulnerability could potentially<\/a> impact a significant number of online businesses. The severity of this issue is further heightened by the fact that even an attacker with only subscriber-level access can exploit this vulnerability, leading to potential system<\/a> compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

Abandoned Cart<\/a> Pro for WooCommerce |<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The Abandoned Cart Pro for WooCommerce plugin contains an authenticated arbitrary file upload vulnerability<\/a> due to missing file type validation in the wcap_add_to_cart_popup_upload_files function. This means that a user with subscriber-level access or above can upload arbitrary<\/a> files on the server where the plugin is installed. Once uploaded, these files could potentially be executed either remotely<\/a> or locally depending on the server configuration, thus leading to a system compromise or data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s an example of how an attacker might exploit this vulnerability by sending a POST request<\/a> to the server with a crafted JSON payload containing the malicious file:<\/p>\n

POST \/upload_file HTTP\/1.1\nHost: target.example.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"file\"; filename=\"malicious.php\"\nContent-Type: application\/x-php\n[...malicious PHP code...]\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
Please note this is a simplified example and actual attack vectors could vary based on the server configuration and security<\/a> measures in place.<\/p>\n","protected":false},"excerpt":{"rendered":"
