Affected Products

Product | Affected Versions

Integration for Pipedrive and Contact Form 7, WPForms, Elementor, Ninja Forms plugin for WordPress | Up to and including 1.2.3

How the Exploit Works

The vulnerability exists due to the unsafe deserialization of untrusted input within the verify_field_val() function in the plugin. This can allow an unauthenticated attacker to inject a malicious PHP Object into the server, leading to arbitrary code execution. When combined with a POP (Property Oriented Programming) chain in the Contact Form 7 plugin, the attacker can delete arbitrary files on the server, potentially deleting the wp-config.php file which leads to a Denial of Service attack or even remote code execution.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited:

POST /wp-admin/admin-ajax.php?action=pipedrive_cf7_integration HTTP/1.1
Host: vulnerable-website.com
Content-Type: application/x-www-form-urlencoded
cf7_form_id=1&form_data=O%3A8%3A%22stdClass%22%3A1%3A%7Bs%3A5%3A%22field%22%3BO%3A11%3A%22PipedriveAPI%22%3A1%3A%7Bs%3A6%3A%22delete%22%3Bs%3A12%3A%22wp-config.php%22%3B%7D%7D

In this example, the attacker sends a POST request to the vulnerable endpoint with a specially crafted `form_data` parameter that contains a serialized PHP object, which when deserialized, triggers the deletion of the wp-config.php file.

Mitigation Guidance

As a mitigation measure, it is recommended to apply the vendor patch as soon as it becomes available. In the meantime, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help to detect and prevent exploitation attempts.
