Generally, symbolic references are not a good idea, especially when combined with names you get from outside! Also, I don't know how this is passing strict -- @names is undeclared, and if I'm not mistaken strict 'refs' disables symbolic references. Try instead using a hash (also added CGI functions rather than raw HTML, and string interpolation)...

use strict;
use warnings;
use CGI;
my $q = CGI->new;
my @names = $q->param;
my %param;

foreach my $name (@names)
{
   $param{$name} = $q->param($name);
   print "$name: $param{$name}", $q->br;
}

Or, more concisely:

use strict;
use warnings;
use CGI;
my $q = CGI->new;
my %params = map { $_, $q->param($_) } ($q->param);
print join $q->br, map { "$_: $params{$_}" } ($q->param);
