Can a WAF block it? Partly. The vulnerability involves command injection via the time_tzsetup.cgi endpoint, which is accessed over HTTP. A WAF can detect unusual command injection syntax in requests to this specific CGI script, which normal users would not send. A WAF rule can match command injection payload in time_tzsetup.cgi parameter. No tracked WAF vendor has published a rule for this CVE yet, so you would write it yourself.
