(in versions v1 r14 through v1 r10)
Title
UIDs reserved for system accounts must not be assigned to non-system accounts. (Cat II impact)
Discussion
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 Content
Check the UID assignments of all accounts. # more /etc/passwd Confirm all accounts with a UID of 128 and below are used by a system account. If a UID reserved for system accounts (0-128) is used by a non-system account, this is a finding.
Fix Text
Using the usermod command, change the UID numbers for non-system accounts with reserved UIDs (those less or equal to 128). # usermod -u <uid> login Alternatively, smit can be used for this same purpose. #smitty users
