AlienVault OTX Vulnerabilities

AlienVault OTX Malware

wp-module-data

Several Newfold plugins are vulnerable to Authentication Bypass. The vulnerability exists because the plugins bundle the wp-module-data module. In the module, the `authenticate()` method — registered on the `rest_authentication_errors` filter and therefore evaluated for every unauthenticated REST API request — performs an HMAC-style Bearer token comparison that degenerates when `HiiveConnection::get_auth_token()` returns `false`: PHP coerces `strrev(false)` to `strrev('')`, collapsing the secret salt to the publicly known constant `hash('sha256', '') = e3b0c44...`, while all remaining hash inputs (HTTP method, request URL, raw request body, and the `X-Timestamp` header) remain fully attacker-controlled. This makes it possible for unauthenticated attackers to compute a valid Bearer token entirely offline, pass the token equality check, and have `wp_set_current_user()` invoked against the first administrator returned by `get_users(['role' => 'administrator'])`, granting full administrator-level access and enabling arbitrary REST API operations such as creating new administrator accounts and achieving complete site takeover. Vulnerable versions are WP Plugin Crazy Domains (<= 2.5.2), WP Plugin Web (<= 2.3.4), WP Plugin Hostgator (<= 3.1.0), WP Plugin Bluehost (<= 4.17.1). The affected module is vulnerable in versions up to, and including, 2.9.4.

The vulnerability arises from the wp-module-data module's `authenticate()` method, which is hooked into the `rest_authentication_errors` filter and invoked on every unauthenticated REST API request. If `HiiveConnection::get_auth_token()` returns false, PHP coerces the token to an empty string, causing the secret salt to collapse to a known constant hash value. Since other inputs to the HMAC are attacker-controlled, an attacker can compute a valid Bearer token offline. Passing this token bypasses authentication, causing `wp_set_current_user()` to set the current user to the first administrator returned by `get_users(['role' => 'administrator'])`. This grants full administrator privileges, enabling arbitrary REST API operations and complete site compromise. Affected versions include WP Plugin Crazy Domains (<= 2.5.2), WP Plugin Web (<= 2.3.4), WP Plugin Hostgator (<= 3.1.0), WP Plugin Bluehost (<= 4.17.1), and the vulnerable module itself up to 2.9.4.
