Administrator password disclosure via phpcgi authentication bypass
Published May 1, 2023 · Updated Jan 30, 2025
Authentication bypass in D-Link DIR-879 version 105A1 allows remote attackers to retrieve the administrator password through phpcgi. The phpcgi handler returns stored administrator credentials to a crafted unauthenticated request instead of enforcing the management interface's authentication check. Network access to the router's management service is sufficient, and the documented consequence is credential disclosure rather than configuration changes or service interruption.
