TITLE

plural NETGEAR Classic buffer overflow vulnerability in device

Trust: 0.8

sources: JVNDB: JVNDB-2017-015009

DESCRIPTION

Certain NETGEAR devices are affected by a buffer overflow by an unauthenticated attacker. This affects R6400 before 1.0.1.24, R6400v2 before 1.0.2.32, R6700 before 1.0.1.22, R6900 before 1.0.1.22, R7000 before 1.0.9.4, R7000P before 1.0.0.56, R6900P before 1.0.0.56, R7100LG before 1.0.0.32, R7300 before 1.0.0.54, R7900 before 1.0.1.18, R8300 before 1.0.2.104, and R8500 before 1.0.2.104. plural NETGEAR A classic buffer overflow vulnerability exists on the device.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR R6400, etc. are all wireless routers from NETGEAR. A buffer error vulnerability exists in many NETGEAR products, which originates from incorrect boundary checks. A remote attacker can use this vulnerability to execute arbitrary code on the system or cause a denial of service with a specially crafted request. This affects R6400 prior to 1.0.1.24, R6400v2 prior to 1.0.2.32, R6700 prior to 1.0.1.22, R6900 prior to 1.0.1.22, R7000 prior to 1.0.9.4, R7000P prior to 1.0.0.56, R6900P prior to 1.0.0.56, R7100LG prior to 1.0.0.32, R7300 prior to 1.0.0.54, R7900 prior to 1.0.1.18, R8300 prior to 1.0.2.104, and R8500 prior to 1.0.2.104
