CVE-2026-15485Public exploitNetwork attack vector

Authenticated command execution via unescaped DNS lookup inputs

Published Jul 12, 2026 · Updated Jul 12, 2026

OS command injection in TRENDnet TEW-821DAP 1.11B03 allows remote authenticated users to execute commands through the DNS lookup handler. The /goform/tools_nslookup handler passes unverified nslookup_target and dns_server values to sprintf, then supplies the resulting nslookup command to system(). Authenticated web-management access is required, and injected commands run with the CGI process's device privileges.
