Unauthenticated code execution via stack overflow
Published Apr 22, 2020 · Updated Aug 5, 2024
Stack-based buffer overflow in NETGEAR XR500 firmware before 2.3.2.32 allows remote attackers to execute code without authentication. The vendor identifies a pre-authentication stack overflow but does not disclose the affected service, input field, or unsafe memory operation. Exploitation requires adjacent-network access and can compromise confidentiality, integrity, and availability on the router.
