An issue was discovered affecting a backup feature where a crafted POST request returns the current configuration of the device in cleartext, including the administrator password. No authentication is required. Affected devices: Wavlink WN575A3, Wavlink WN579G3, Wavlink WN531A6, Wavlink WN535G3, Wavlink WN530H4, Wavlink WN57X93, Wavlink WN572HG3, Wavlink WN575A4, Wavlink WN578A2, Wavlink WN579G3, Wavlink WN579X3, and Jetstream AC3000/ERAC3000

An issue was discovered where there are multiple externally accessible pages that do not require any sort of authentication, and store system information for internal usage. The devices automatically query these pages to update dashboards and other statistics, but the pages can be accessed externally without any authentication. All the pages follow the naming convention live(string).shtml. Among the information disclosed is: interface status logs, IP address of the device, MAC address of the device, model and current firmware version, location, all running processes, all interfaces and their statuses, all current DHCP leases and the associated hostnames, all other wireless networks in range of the router, memory statistics, and components of the configuration of the device such as enabled features. Affected devices: Affected devices are: Wavlink WN530HG4, Wavlink WN575A3, Wavlink WN579G3,Wavlink WN531G3, Wavlink WN533A8, Wavlink WN531A6, Wavlink WN551K1, Wavlink WN535G3, Wavlink WN530H4, Wavlink WN57X93, WN572HG3, Wavlink WN578A2, Wavlink WN579G3, Wavlink WN579X3, and Jetstream AC3000/ERAC3000
