CVE-2026-9439Public exploitNetwork attack vector

Authenticated command execution via interface injection

Published May 25, 2026 · Updated May 25, 2026

Command injection in Edimax BR-6675nD 1.12 allows remote authenticated users to execute operating-system commands via a crafted interface parameter. The stainfo handler at /goform/stainfo incorporates the user-controlled interface argument into an operating-system command without neutralizing command syntax. Reachability requires low-privilege authenticated access to the router's web management interface; no user interaction is required.
