A critical buffer overflow vulnerability (CVE-2026-15484) exists in the `sub_41EC14` function within the `/goform/tools_nslookup` component of the TRENDnet TEW-821DAP 1.12B01 wireless access point, which can be exploited remotely due to improper handling of the ssi element, potentially leading to arbitrary code execution on an End-of-Life device.

A critical remote command injection vulnerability (CVE-2026-15481) has been discovered in Trendnet TEW-635BRM routers up to version 1.00.03, allowing attackers to execute arbitrary commands by manipulating the 'ipoa_ipaddr' argument in the 'ipoa_test' function, with public exploits available for this End-of-Life product.

CVE-2026-15480 describes a stack-based buffer overflow vulnerability in the Trendnet TEW-635BRM router firmware, specifically in the start_httpd function within the /sbin/rc component's Web Service, which can be exploited remotely by manipulating the 'device_name' argument, potentially leading to arbitrary code execution; an exploit is publicly available, but the product is End-of-Life (EOL) since 2011, and the vendor advises users to switch devices.

A stack-based buffer overflow vulnerability (CVE-2026-10123) exists in TRENDnet TEW-432BRP version 3.10B20 within the formSetDomainFilter function, allowing a remote attacker to execute arbitrary code by manipulating specific arguments in a request to /goform/formSetDomainFilter.

TRENDnet TEW-432BRP version 3.10B20 is vulnerable to a stack-based buffer overflow via manipulation of the ip/mask/gateway arguments in the formSetRoute function of the /goform/formSetRoute file, enabling remote attackers to potentially execute arbitrary code.

A buffer overflow vulnerability exists in TRENDnet TEW-821DAP version 1.12B01, allowing a remote attacker to execute arbitrary code by manipulating the 'str' argument in the auto_update_firmware function of the Firmware Update component.
