## Technical details

This is an OS command injection vulnerability (CWE-78) in the /goform/asp_WlanMP endpoint of Edimax BR-6214K firmware version 1.40. The vulnerable component fails to sanitize the ateFunc parameter before passing it to a system() call that constructs a shell command (/bin/rftest.sh). An authenticated attacker can inject shell metacharacters (e.g., ;id;#) to execute arbitrary commands with the privileges of the Boa web server, which runs as root. Authentication is required (valid web-management credentials), but the vulnerability is remotely exploitable over the network. A public proof-of-concept exists; the vendor did not respond to early disclosure.
