Check: GEN001870

VMware ESX 3 Server: GEN001870 (in version v1 r2)

Title

Local initialization files must be group-owned by the user's primary group or root. (Cat II impact)

Discussion

Local initialization files are used to configure the user's shell environment upon login. Malicious modification of these files could compromise accounts upon logon.

Check Content

Check user home directories for local initialization files group-owned by a group other than the user's primary group or root. 1. List user accounts and their primary GID. # cut -d : -f 1,4 /etc/passwd 2. Check local initialization files for each user. # ls -alL ~USER/.login ~USER/.cshrc ~USER/.logout ~USER/.profile ~USER/.bash_profile ~USER/.bashrc ~USER/.bash_logout ~USER/.env ~USER/.dtprofile ~USER/.dispatch ~USER/.emacs ~USER/.exrc 3. If any file is not group-owned by root or the user's primary GID, this is a finding.

Fix Text

Change the group owner of the local initialization file to the user's primary group, or root. # chgrp [USER's primary GID] ~USER/[local initialization file]
