RegistrationMagic <= 6.0.7.1 - Privilege Escalation via admin_order

The RegistrationMagic plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 6.0.7.1. This is due to the 'add_menu' function is accessible via the 'rm_user_exists' AJAX action and allows arbitrary updates to the 'admin_order' setting. This makes it possible for unauthenticated attackers to injecting an empty slug into the order parameter, and manipulate the plugin's menu generation logic, and when the admin menu is subsequently built, the plugin adds 'manage_options' capability for the target role. Note: The vulnerability can only be exploited unauthenticated, but further privilege escalation requires at least a subscriber user.

JUNG eNet SMART HOME server 2.2.1/2.3.1 Privilege Escalation via setUserGroup

eNet SMART HOME server 2.2.1 and 2.3.1 contains a privilege escalation vulnerability due to insufficient authorization checks in the setUserGroup JSON-RPC method. A low-privileged user (UG_USER) can send a crafted POST request to /jsonrpc/management specifying their own username to elevate their account to the UG_ADMIN group, bypassing intended access controls and gaining administrative capabilities such as modifying device configurations, network settings, and other smart home system functions.
