CVE-2021-34983

Credential disclosure via unauthenticated configuration access

Published May 7, 2024 · Updated Aug 4, 2024

Information disclosure in NETGEAR Multiple Routers 1.0.11.116_10.2.100 allows network-adjacent attackers to read stored credentials. The default TCP port 80 httpd service exposes system configuration information without first authenticating the request. Access requires adjacency to the router network, and the disclosed credentials enable further compromise.
