Automation from Windows to AIX - Telnet and su using perl

Here is my requirement to automate the deployment procedure for my project.

Telnet to AIX box (say SERVER1) from windows machine (with USER1)
Select the server to login say "SERVER2"
su as different user say "USER2"(Owner of the deployed files)
Execute the script (Script has so many functionality like ftp, changing permission, removing control-M, calling sub scripts)
Exit from su environment
Exit from telnet environment

Look at my perl Code :

use Net::Telnet;
my $telnet = new Net::Telnet(Timeout => 30,Errmode => 'die');
$telnet->open("SERVER1") or die "Connection failed $telnet->errmsg ";
print "connected\n";
$telnet->waitfor('/login: $/i');
$telnet->print("USER1") or die $telnet->errmsg;
$telnet->waitfor('/password: $/i');
$telnet->print("USER1-PASSWORD") or die $telnet->errmsg;
print "logged in first level\n";
$telnet->waitfor('/Enter Selection $/i');
$telnet->print("SERVER2") or die $telnet->errmsg;
print "Logged into SERVER2\n";
$telnet->cmd("touch test") or die $telnet->errmsg;
print "touch test executed\n";
==============###script is working till this part#####==========
$telnet->cmd("su - USER2");
$telnet->waitfor('Password: $/i');
$telnet->print("USER2-PASSWORD") or die $telnet->errmsg;
print "Logged in to USER2\n";
$telnet->cmd("sh script.sh") or die $telnet->errmsg;
print "successfully executed\n";
$telnet->cmd("exit");
$telnet->cmd("exit");

Limitation :

I can't use SUDO or EXPECT. Because I am not the root user to use sudo. Expect is not installed in the server.
Script has required permission to execute it from USER1 environment. But that script has to execute as USER2 else all files deployed will have USER1 as owner. This can be done using sudo, but this is very limited access environment, so I wont get access to sudo.

So I am looking for a su script sitting in USER1 environment to login without password and execute the script and exit from there.

Please let me know if there is any other possibility to get this work done.

telnetrc

telnetrc(4)							   File Formats 						       telnetrc(4)

NAME

       telnetrc - file for telnet default options

DESCRIPTION

       The   .telnetrc	file  contains commands that are executed when a connection is established on a per-host basis. Each line in the file con-
       tains a host name, one or more spaces or tabs, and a telnet(1) command. The host name, DEFAULT, matches all hosts. Lines beginning with the
       pound  sign (#) are interpreted as comments and therefore ignored. telnet(1) commands are case-insensitive to the contents of the .telnetrc
       file.

       The  .telnetrc file is retrieved from each user's  HOME directory.

EXAMPLES

       Example 1: A sample file.

       In the following example, a .telnetrc file executes the telnet(1) command, toggle:

       weirdhost toggle crmod
       # Always export $PRINTER
       DEFAULT environ export PRINTER

       The lines in this file indicate that the toggle argument crmod, whose default value is "off" (or FALSE), should be enabled when	connecting
       to  the	system weirdhost. In addition, the value of the environment variable  PRINTER should be exported to all systems. In this case, the
       DEFAULT keyword is used in place of the host name.
