CVE-2019-20679

Protected-data access via missing function authorization

Published Apr 15, 2020 · Updated Aug 5, 2024

Missing function-level access control in NETGEAR MR1100 firmware before 12.06.08.00 allows attackers to read or alter protected data. NETGEAR has not disclosed which firmware endpoint or function omits authorization, nor the exact operation performed on attacker-controlled input. Exploitation requires adjacent-network access and user interaction; successful access affects protected data but does not interrupt availability.
