What is that PoC in the issue doing? They check e which is not set after first line in the function:
func send(addr, server, sni string) int {
c0, e := net.Dial("tcp", addr)
if e != nil {
log.Fatal(e)
}
c1 := tls.Client(c0, &tls.Config{
ServerName: server,
InsecureSkipVerify: true,
})
c2 := tls.Client(c1, &tls.Config{
ServerName: sni,
InsecureSkipVerify: true,
})
c2.SetDeadline(time.Now().Add(2 * time.Minute))
s := fmt.Sprintf("GET / HTTP/1.1\r\nHost: %s\r\nUser-Agent: curl/7.68.0\r\n\r\n", sni)
//b := make([]byte, 4096)
l, _ := c2.Write([]byte(s))
log.Println(l)
if e != nil {
return 0
}
log.Printf("%s->%s->%s\n", addr, server, sni)
return l
}
