Title

Local initialization files must not have extended ACLs. (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 with extended ACLs. # cut -d : -f 6 /etc/passwd | xargs -n1 -IDIR ls -alL DIR/.login DIR/.cshrc DIR/.logout DIR/.profile DIR/.bash_profile DIR/.bashrc DIR/.bash_logout DIR/.env DIR/.dtprofile DIR/.dispatch DIR/.emacs DIR/.exrc If the permissions include a "+", the file has an extended ACL, this is a finding.

Fix Text

Remove the extended ACL from the local initialization file(s).
