V-224728mediumIBM Hardware Configuration Definition (HCD) resources are not properly defined and protected.Program products can run with sensitive system privileges, and potentially can circumvent system controls. Failure to properly control access to program product resources could result in the compromise of the operating system environment, and compromise the confidentiality of customer data. Many utilities assign resource controls that can be granted to systems programmers only in greater than read authority. Resources are also granted to certain nonsystems personnel with read only authority.
