VAR-202004-1336
Vulnerability from variot - Updated: 2023-12-18 12:17Certain NETGEAR devices are affected by a buffer overflow by an authenticated user. This affects R7800 before 1.0.2.36, PLW1000v2 before 1.0.0.14, and PLW1010v2 before 1.0.0.14. NETGEAR R7800 , PLW1000v2 , PLW1010v2 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 R7800, etc. are all products of NETGEAR. NETGEAR R7800 is a wireless router. NETGEAR PLW1000 is a power line communication modem. NETGEAR PLW1010 is a power line communication modem.
NETGEAR R7800 prior to 1.0.2.36, PLW1000v2 prior to 1.0.0.14 and PLW1010v2 prior to 1.0.0.14 have a buffer overflow vulnerability, which originated when the network system or product performed operations on the memory and did not correctly verify the data boundary, resulting in An erroneous read and write operation was performed on the associated other memory location. An attacker could use this vulnerability to cause a buffer overflow or heap overflow
