Data alteration and service interruption via stack overflow
Published Dec 26, 2021 · Updated Aug 4, 2024
Stack-based buffer overflow in NETGEAR D7000 firmware before 1.0.1.82 allows attackers to alter data or interrupt service. NETGEAR has not disclosed the affected interface or function, the attacker-controlled input, or the unsafe operation that overwrites the stack. Exploitation requires adjacent-network access but no authentication or user interaction; the public record does not identify whether interruption appears as a hang, crash, or reboot.
