CVE-2012-6340Public exploit

Local authentication bypass via hardcoded serial credential

Published Feb 6, 2020 · Updated Aug 6, 2024

Authentication flaw in NETGEAR WGR614 v7 and v9 allows local users to access serial programming via a hardcoded credential. The serial programming interface accepts an embedded credential instead of enforcing unique authentication, exposing device information to anyone with physical access. Exploitation requires direct physical access to the router; the record describes confidentiality impact without integrity or availability impact.
