CVE-2026-9423Public exploitNetwork attack vector

Authenticated command execution via unsanitized POST parameter

Published May 25, 2026 · Updated May 25, 2026

OS command injection in the mp POST handler in Edimax BR-6675nD 1.12 allows remote authenticated users to execute arbitrary commands. The /goform/mp endpoint supplies the command parameter to the mp function without neutralizing command-control characters before execution. Administrative privileges and network access to the web management interface are required; successful exploitation can read or alter router data and interrupt service.
