VAR-202004-1717
Vulnerability from variot - Updated: 2023-12-18 13:12Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects D7800 before 1.0.1.30, EX2700 before 1.0.1.28, R6100 before 1.0.1.20, R7500 before 1.0.0.118, R7500v2 before 1.0.3.24, R7800 before 1.0.2.40, R9000 before 1.0.2.52, WN2000RPTv3 before 1.0.1.20, WN3000RPv3 before 1.0.2.50, WN3100RPv2 before 1.0.0.56, WNDR3700v4 before 1.0.2.96, WNDR4300 before 1.0.2.98, WNDR4300v2 before 1.0.0.50, and WNDR4500v3 before 1.0.0.50. 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 D7800, etc. are all products of NETGEAR. NETGEAR D7800 is a wireless modem. NETGEAR WNDR3700 is a wireless router. NETGEAR R6100 is a wireless router. 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 D7800 prior to 1.0.1.30, EX2700 prior to 1.0.1.28, R6100 prior to 1.0.1.20, R7500 prior to 1.0.0.118, R7500v2 prior to 1.0.3.24, R7800 prior to 1.0.2.40, R9000 prior to 1.0.2.52, WN2000RPTv3 prior to 1.0.1.20, WN3000RPv3 prior to 1.0.2.50, WN3100RPv2 prior to 1.0.0.56, WNDR3700v4 prior to 1.0.2.96, WNDR4300 prior to 1.0.2.98, WNDR4300v2 prior to 1.0.0.50, and WNDR4500v3 prior to 1.0.0.50

"data": "Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects D7800 before 1.0.1.30, EX2700 before 1.0.1.28, R6100 before 1.0.1.20, R7500 before 1.0.0.118, R7500v2 before 1.0.3.24, R7800 before 1.0.2.40, R9000 before 1.0.2.52, WN2000RPTv3 before 1.0.1.20, WN3000RPv3 before 1.0.2.50, WN3100RPv2 before 1.0.0.56, WNDR3700v4 before 1.0.2.96, WNDR4300 before 1.0.2.98, WNDR4300v2 before 1.0.0.50, and WNDR4500v3 before 1.0.0.50. 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 D7800, etc. are all products of NETGEAR. NETGEAR D7800 is a wireless modem. NETGEAR WNDR3700 is a wireless router. NETGEAR R6100 is a wireless router. 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 D7800 prior to 1.0.1.30, EX2700 prior to 1.0.1.28, R6100 prior to 1.0.1.20, R7500 prior to 1.0.0.118, R7500v2 prior to 1.0.3.24, R7800 prior to 1.0.2.40, R9000 prior to 1.0.2.52, WN2000RPTv3 prior to 1.0.1.20, WN3000RPv3 prior to 1.0.2.50, WN3100RPv2 prior to 1.0.0.56, WNDR3700v4 prior to 1.0.2.96, WNDR4300 prior to 1.0.2.98, WNDR4300v2 prior to 1.0.0.50, and WNDR4500v3 prior to 1.0.0.50",
