You will probably need to do this in two stages:
1) Read the parameter file and use it to write a shell script file containing alternate "useradd" and "passwd" commands. Make the file executable.
2) Run the new script file.
The original issue is no doubt that the main script and the passwd command are both reading from STDIN. Thus the passwd command reads characters from the parameter file. Note: This method is not suitable for setting passwords in a script because of the way the passwd command does not tolerate typeahead.

NAME

SYNOPSIS
checksecurity
DESCRIPTION
The checksecurity command runs a small collection of simple system checks which are designed to catch a few common security issues. check-
security is run by cron in a daily basis.
CONFIGURATION
The checksecurity.conf file defines several configuration variables: MAILTO, CHECK_DISKFREE, CHECK_PASSWD and CHECK_SETUID LOGDIR. Each is
described below.
The checksecurity program works with a collection of plugins which are located in /usr/share/checksecurity and are configured individually
by their own configuration file.
CHECK_PASSWD If this is set to TRUE then the check-passwd script will be invoked. This script is designed to report upon system accounts
which have no passwords. CHECK_DISKFREE If this is set to TRUE then the check-diskfree script will be invoked and will allow an alert to
be sent if there is any mounted partition is running short on disk space. CHECK_SETUID If this is set to TRUE then the check-setuid script
will be invoked, this will compare the setuid binaries upon the system to those that existed previously and show the differences.
