TITLE

plural NETGEAR Out-of-bounds write vulnerabilities in devices

Trust: 0.8

sources: JVNDB: JVNDB-2018-016318

DESCRIPTION

Certain NETGEAR devices are affected by a stack-based buffer overflow by an authenticated user. This affects DM200 before 1.0.0.52, R7500 before 1.0.0.122, R7800 before 1.0.2.42, R8900 before 1.0.3.10, R9000 before 1.0.3.16, WNDR3700v4 before 1.0.2.96, WNDR4300 before 1.0.2.98, WNDR4300v2 before 1.0.0.54, WNDR4500v3 before 1.0.0.54, and WNR2000v5 before 1.0.0.64. 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 R7800, 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. This affects DM200 prior to 1.0.0.52, R7500 prior to 1.0.0.122, R7800 prior to 1.0.2.42, R8900 prior to 1.0.3.10, R9000 prior to 1.0.3.16, WNDR3700v4 prior to 1.0.2.96, WNDR4300 prior to 1.0.2.98, WNDR4300v2 prior to 1.0.0.54, WNDR4500v3 prior to 1.0.0.54, and WNR2000v5 prior to 1.0.0.64
