Authenticated stack buffer overflow
Published Apr 28, 2020 · Updated Aug 5, 2024
NETGEAR router firmware before the listed fixed versions allows remote authenticated users to trigger a stack-based buffer overflow through management interfaces. The affected request-handling code copies attacker-controlled input into a fixed-size stack buffer without adequate bounds checking, but public records do not identify the exact function or request parameter. Authentication is required, and the overflow can compromise device confidentiality, integrity, and availability; the exact post-overflow outcome is not specified.
