CVE-2019-20730Network attack vector

Unauthenticated data access via undisclosed SQL injection

Published Apr 16, 2020 · Updated Aug 5, 2024

SQL injection in NETGEAR router, gateway, and extender firmware allows remote attackers to read or modify data over the network. NETGEAR has not disclosed the affected endpoint, parameter, query construction, or other code-level mechanism that permits untrusted input to alter an SQL statement. No authentication or user interaction is required, and the published vendor assessment limits the consequence to confidentiality and integrity.
