Technical details

A command injection vulnerability (CWE-77) exists in the web-based management interface of the Edimax BR-6428nS V3 router running firmware version 1.15. The flaw is located within the WLAN configuration functionality, where the application fails to sufficiently validate user-supplied input before passing it to a system shell. An authenticated attacker with network access can submit crafted input containing shell metacharacters to vulnerable parameters. Successful exploitation allows for arbitrary command execution on the underlying operating system with the privileges of the web service, potentially leading to full device compromise.
