Vulnerability from variot
Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects D3600 before 1.0.0.76, D6000 before 1.0.0.76, D6200 before 1.1.00.32, D7000 before 1.0.1.68, JR6150 before 1.0.1.18, PR2000 before 1.0.0.28, R6020 before 1.0.0.38, R6050 before 1.0.1.18, R6080 before 1.0.0.38, R6120 before 1.0.0.46, R6220 before 1.1.0.80, R6260 before 1.1.0.40, R6700v2 before 1.2.0.36, R6800 before 1.2.0.36, R6900v2 before 1.2.0.36, WNR2020 before 1.1.0.62, 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 D3600, etc. are all products of NETGEAR. NETGEAR D3600 is a wireless modem. NETGEAR JR6150 is a wireless router. NETGEAR PR2000 is a wireless router.
There are buffer error vulnerabilities in many NETGEAR products. The vulnerability stems from the fact that when a network system or product performs an operation on memory, the data boundary is not correctly verified, resulting in an incorrect read and write operation to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow

"data": "Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects D3600 before 1.0.0.76, D6000 before 1.0.0.76, D6200 before 1.1.00.32, D7000 before 1.0.1.68, JR6150 before 1.0.1.18, PR2000 before 1.0.0.28, R6020 before 1.0.0.38, R6050 before 1.0.1.18, R6080 before 1.0.0.38, R6120 before 1.0.0.46, R6220 before 1.1.0.80, R6260 before 1.1.0.40, R6700v2 before 1.2.0.36, R6800 before 1.2.0.36, R6900v2 before 1.2.0.36, WNR2020 before 1.1.0.62, 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 D3600, etc. are all products of NETGEAR. NETGEAR D3600 is a wireless modem. NETGEAR JR6150 is a wireless router. NETGEAR PR2000 is a wireless router. \n\r\n\r\nThere are buffer error vulnerabilities in many NETGEAR products. The vulnerability stems from the fact that when a network system or product performs an operation on memory, the data boundary is not correctly verified, resulting in an incorrect read and write operation to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow",
