Unauthenticated buffer overflow via pre-authentication request
Published Apr 28, 2020 · Updated Aug 5, 2024
Buffer overflow in NETGEAR routers and extenders before listed fixed versions allows remote attackers to cause unspecified impact via network requests. The pre-authentication request parser copies attacker-controlled data into a fixed-size buffer without adequate bounds checks; the vendor does not identify the exact function or parameter. Unauthenticated attackers on an adjacent network can reach the service without login, while consequences beyond the overflow are not disclosed.
