CVE-2026-15481 is a remote command injection vulnerability affecting Trendnet TEW-635BRM firmware up to version 1.00.03. The flaw is reported in the IPoA WAN Connection Setup component, specifically in the ipoa_test function within /sbin/rc. Insufficient neutralization of attacker-controlled input supplied through the ipoa_ipaddr argument allows crafted input to be interpreted as operating system commands. Successful exploitation could enable arbitrary command execution on the affected device. Public exploit information is available. The affected product is end-of-life and no longer supported by the vendor.
