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

A high-severity vulnerability, CVE-2025-7437, has been identified in the Ebook Store plugin for WordPress. This flaw allows unauthenticated attackers to upload arbitrary files due to missing file type validation, leading to potential system compromise or data leakage. This vulnerability has a wide impact as it affects all versions up to 5.8012 of the plugin, which is widely used by publishers and online stores on the WordPress platform<\/a>. This vulnerability is particularly concerning due to its potential to enable<\/a> remote code execution if exploited successfully.<\/p>\n

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

CVE ID: CVE-2025-7437
\nSeverity: Critical (9.8\/10)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system compromise<\/a> or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Ebook Store Plugin for WordPress<\/a> | Up to and including 5.8012<\/p>\n

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

The vulnerability lies in the ebook_store_save_form function which lacks proper validation<\/a> of file types. This allows an attacker to upload any file<\/a> to the server, including executable files or scripts, without requiring any form of authentication. Once uploaded, these files can be triggered to execute arbitrary code<\/a>, potentially gaining control over the server and enabling the attacker to access, modify, or delete data, or even create new accounts with full user rights.<\/p>\n

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

Below is a simplified, conceptual example of how an HTTP request exploiting the vulnerability<\/a> might look. This example assumes the attacker is uploading a malicious PHP file that can enable remote<\/a> code execution:<\/p>\n

POST \/wp-content\/plugins\/ebook-store\/upload.php HTTP\/1.1\nHost: target.example.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"file\"; filename=\"exploit.php\"\nContent-Type: application\/x-php\n\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
This request uploads a PHP file<\/a> named ‘exploit.php’ which, when accessed, would run any command passed via the ‘cmd’ URL parameter.<\/p>\n
Mitigation<\/strong><\/p>\n
The most effective mitigation is to apply the vendor-supplied patch. If that is not immediately possible, implementing protections via a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation against potential attacks.<\/p>\n","protected":false},"excerpt":{"rendered":"
