McKesson Horizon Clinical Infrastructure, also known as McKesson HCI, utilizes hardcoded passwords
for Oracle database access. HCI serves as the patient record datastore for the majority of McKesson applications. There are two components to an HCI implementation: the Infrastructure (or Master) server
and the database back-end. The HCI Infrastructure Server has an Oracle client installed that initializes
OCI/sqlplus connections to the Oracle database back-end. A file on each HCI Infrastructure server
contains the database account usernames and their respective passwords, /usr/local/bin/password. Content from /usr/local/bin/password is shown:

Despite having a "central" password file that contains the credential information, much of the credentials
are hardcoded throughout binaries and scripts that are shipped as part of the HCI Infrastructure server.

# cd /u/live
# find . -type f -print | xargs grep ccnull | wc -l
85

Here is some context of how the credentials are used throughout the HCI code:

# find . -type f -print | xargs grep ccnull        
./RUN_dmArchive:remote_db=`sqlplus -s ccdba/ccnulls$DB_SPEC_IF_REMOTE << EOF
./all_ord:LOGIN=ccdba/ccnulls
./bin/BatchDischarge:ora_user="ccdba/ccnulls$DB_SPEC_IF_REMOTE"
./bin/CheckDischargeRpts:ora_user="ccdba/ccnulls$DB_SPEC_IF_REMOTE"
./bin/Make_iv_template:sqlldr ccdba/ccnulls iv_bottle >> $LOG
./bin/Make_iv_template:ORD_SEQ=`sqlplus -S ccdba/ccnulls$DB_SPEC_IF_REMOTE <<- ENDSQL

McKesson supports HCI on the AIX, HP-UX, and Linux passwords. The nature of hardcoded passwords implies
that for every customer that has purchased HCI, the credentials for all of these role accounts are the same across the installations. 

According to the following press release, http://www.oracle.com/corporate/press/2008_mar/em-mckesson.html, McKesson software is installed in 70% of hospitals within the US. HCI serves as the core infrastructure
component of other McKesson applications such as Horizon Lab, Horizon Patient Folder, Horizon CareLink,
Horizon Expert Documentation, etc.
