How the Exploit Works

This vulnerability arises due to insufficient file path validation in the delete_entry_files() function of the Everest Forms (Pro) plugin. An attacker can exploit this flaw to delete arbitrary files on the server. However, this action requires an admin to trigger the deletion via deletion of a form entry. If a crucial file such as wp-config.php is deleted, it can lead to remote code execution.

Conceptual Example Code

This is a conceptual example of a malicious HTTP request that an attacker could use to exploit this vulnerability:

POST /wp-admin/admin-ajax.php?action=everest_forms_delete_entry_files HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"form_id": "1",
"entry_id": "1",
"file_path": "../../../../wp-config.php"
}

In this example, the attacker is attempting to delete the wp-config.php file, which could lead to remote code execution.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. Always remember to keep your plugins updated to the latest version to avoid known vulnerabilities.
