Authenticated device compromise via buffer overflow
Published Apr 16, 2020 · Updated Aug 5, 2024
Buffer overflow in NETGEAR R7000 firmware before 1.0.9.42 allows remote authenticated users to cause unspecified impact via crafted input. NETGEAR has not disclosed the affected component, input field, or memory-copy operation that permits attacker-controlled data to exceed its destination buffer. Exploitation requires adjacent-network access, an authenticated session, and, according to the vendor and CNA assessments, user interaction; no public source specifies whether the result is a crash or code execution.
