Credential disclosure via pre-redirect HTTP authentication
Published Mar 21, 2023 · Updated Feb 26, 2025
Cleartext transmission in NETGEAR Orbi RBR750 4.6.8.5 allows man-in-the-middle attackers to capture router credentials over HTTP. Even when HTTPS-only access is enabled, an HTTP request prompts for credentials before redirecting, so valid credentials cross the network without encryption. The attacker must know the WiFi password or have Ethernet access to the network, and a user must submit valid router credentials.
