Vendor-supplied user accounts for the WebSphere Application Server must be defined to the ACP.

Vendor-supplied user accounts are defined to the ACP with factory-set passwords during the installation of the WebSphere Application Server (WAS). These user accounts are common to all WAS environments and have access to restricted resources and functions. Failure to delete vendor-supplied user accounts from the ACP may lead to unauthorized access. This exposure could compromise the integrity and availability of system services, applications, and customer data.

Refer to the following report produced by the ACP Data Collection:

ACF2 - ACF2CMDS.RPT(LOGONIDS). RACF - RACFCMDS.RPT(LISTUSER). TSS - TSSCMDS.RPT(@ACIDS).

Automated Analysis requires Additional Analysis. Refer to the following report produced by the z/OS Data Collection:

- PDI(ZWAS0040)

If the CBADMIN user account is not defined to the ACP, this is not a finding.

If the CBADMIN user account is defined to ACP and the password has NOT been changed from the vendor default of CBADMIN, this is a finding with a severity of Category I.

If the CBADMIN user account is defined to the ACP and the password has been changed from the vendor default of CBADMIN, this is a finding with a severity of Category II.

The ISSO will ensure that the CBADMIN user account is removed or not defined to the ACP.
