VAR-202309-0028
Vulnerability from variot - Updated: 2025-06-25 23:16Buffer Overflow vulnerability in NETGEAR R6400v2 before version 1.0.4.118, allows remote unauthenticated attackers to execute arbitrary code via crafted URL to httpd. CBR40 firmware, LAX20 firmware, MK62 A classic buffer overflow vulnerability exists in multiple Netgear products, including firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. NETGEAR R6400v2 is a router from NETGEAR. It is a hardware device that connects two or more networks and acts as a gateway between networks.
NETGEAR R6400v2 has a code execution vulnerability, which is caused by the program failing to properly filter special elements in the constructed code segment
