CVE-2026-94952 Details
Description
A stack-based buffer overflow vulnerability exists in the web management interface of TOTOLINK N150RT (NTR150) firmware V3.4.0-B20201030. It is reachable through the route /boafrm/formPortFw (port-forwarding configuration handler) and is triggered by the ip_subnet and fw_ip request parameters during the rule-addition flow.
A stack-based buffer overflow vulnerability has been identified in the web management interface of the TOTOLINK N150RT (NTR150) router, specifically in firmware version V3.4.0-B20201030. The vulnerability is accessible through the port-forwarding configuration handler at '/boafrm/formPortFw'. It is triggered by the 'ip_subnet' and 'fw_ip' request parameters during the process of adding port forwarding rules. The issue arises because these parameters can be manipulated to exceed the buffer limit, leading to a stack-based overflow.
Users are advised to update to a version of the firmware that addresses this vulnerability. If no update is available, consider disabling the web management interface or using alternative methods to configure the router.
