UIDs reserved for system accounts must not be assigned to non-system accounts.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-11946	GEN000340	SV-38209r1_rule	ECSC-1	Medium

Description
Reserved UIDs are typically used by system software packages. If non-system accounts have UIDs in this range, they may conflict with system software, possibly leading to the user having permissions to modify system files.

Check Text ( C-36258r1_chk )
Check the UID assignments of all accounts. # more /etc/passwd Confirm all accounts with a UID of 99 and below are used by a system account. If a UID reserved for system accounts (0 - 99) is used by a non-system account, this is a finding.

Fix Text (F-31515r1_fix)
Using the passwd command, change the UID numbers for non-system accounts with reserved UIDs (those less or equal to 99). SMH can alternatively be used for this same purpose.
