CVE-2026-8777Public exploitNetwork attack vector

Authenticated command execution via crafted SSID

Published May 18, 2026 · Updated May 18, 2026

Command injection in the Edimax BR-6428nS 1.10 POST handler allows remote authenticated users to execute commands via a crafted SSID. The formStaDrvSetup function processes the stadrv_ssid parameter without neutralizing command elements before downstream execution. Low-privilege access to the web management interface is required, and injected commands run with the web server process's privileges.
