Trust: 0.8

sources: JVNDB: JVNDB-2019-015409

DESCRIPTION

Certain NETGEAR devices are affected by a stack-based buffer overflow by an authenticated user. This affects D3600 before 1.0.0.75, D6000 before 1.0.0.75, D6100 before 1.0.0.63, DM200 before 1.0.0.58, EX2700 before 1.0.1.48, EX6100v2 before 1.0.1.76, EX6150v2 before 1.0.1.76, EX6200v2 before 1.0.1.72, EX6400 before 1.0.2.136, EX7300 before 1.0.2.136, EX8000 before 1.0.1.180, R7800 before 1.0.2.52, R8900 before 1.0.4.2, R9000 before 1.0.4.2, WN2000RPTv3 before 1.0.1.32, WN3000RPv2 before 1.0.0.68, WN3000RPv3 before 1.0.2.70, WN3100RPv2 before 1.0.0.60, WNDR4300v2 before 1.0.0.58, WNDR4500v3 before 1.0.0.58, WNR2000v5 before 1.0.0.68, and XR500 before 2.3.2.32. plural NETGEAR The device is vulnerable to out-of-bounds writes.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR R8900, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow
