Vulnerability Discussion

It is detrimental for operating systems to provide, or install by default, functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and therefore may remain unsecured. They increase the risk to the platform by providing additional attack vectors.

Operating systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions, functions).

The iprutils package provides a suite of utilities to manage and configure SCSI devices supported by the ipr SCSI storage device driver.

Check

Verify the iprutils package has not been installed on the system with the following commands:

$ sudo yum list installed iprutils

iprutils.x86_64 2.4.18.1-1.el8 @anaconda

If the iprutils package is installed and is not documented with the Information System Security Officer (ISSO) as an operational requirement, this is a finding.

Fix

Document the iprutils package with the ISSO as an operational requirement or remove it from the system with the following command:

$ sudo yum remove iprutils
