CVE-2026-1687Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized serverString parameter

Published Jan 30, 2026 · Updated Jan 30, 2026

Command injection in Tenda HG10 firmware US_HG7_HG9_HG10re_300001138_en_xpon allows remote attackers to execute arbitrary commands. The Boa formSamba handler reads serverString with boaGetVar and embeds it in a shell command without validation or sanitization. No authentication is required; a crafted POST request can execute commands with the web server's device privileges and compromise the router.
