TITLE

plural NETGEAR Out-of-bounds write vulnerabilities in devices

Trust: 0.8

sources: JVNDB: JVNDB-2018-016403

DESCRIPTION

Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects WAC505 before 5.0.5.4, WAC510 before 5.0.5.4, WAC120 before 2.1.7, WN604 before 3.3.10, WNAP320 before 3.7.11.4, WNAP210v2 before 3.7.11.4, WNDAP350 before 3.7.11.4, WNDAP360 before 3.7.11.4, WNDAP660 before 3.7.11.4, WNDAP620 before 2.1.7, and WND930 before 2.1.5. 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 WAC505, etc. are all wireless access points (AP) of NETGEAR. There are buffer overflow vulnerabilities in many NETGEAR products, and remote attackers can use this vulnerability to execute arbitrary code by sending specially crafted requests. This affects WAC505 prior to 5.0.5.4, WAC510 prior to 5.0.5.4, WAC120 prior to 2.1.7, WN604 prior to 3.3.10, WNAP320 prior to 3.7.11.4, WNAP210v2 prior to 3.7.11.4, WNDAP350 prior to 3.7.11.4, WNDAP360 prior to 3.7.11.4, WNDAP660 prior to 3.7.11.4, WNDAP620 prior to 2.1.7, and WND930 prior to 2.1.5
