Service interruption or command execution via unchecked SSIDs
Published Aug 7, 2023 · Updated Oct 11, 2024
Buffer overflows in NETGEAR R6900P 1.3.3.154 allow remote authenticated users to interrupt service or execute commands via SSID fields. The ia_ap_setting.cgi handler writes length-unchecked wla_ssid and wlg_ssid request values to NVRAM, and a later function at 0x90744 overflows while using them. Access requires router administration credentials and network reachability; exploitation can cause persistent service interruption or arbitrary command execution.
