Description An issue was discovered where multiple externally accessible pages do not require authentication and store system information for internal usage. These pages follow the naming convention live (string).shtml and can be accessed externally without authentication. The disclosed information includes 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.

Recommendations For each of the affected devices, restrict access to the externally accessible pages that follow the naming convention live (string).shtml to minimize the risk of exploitation. As a temporary workaround, consider disabling external access to these pages until a patch is available. Avoid using these pages for updating dashboards and other statistics until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
