Title

All run control scripts must have mode 0755 or less permissive. (Cat II impact)

Discussion

If the startup files are writable by other users, they could modify the startup files to insert malicious commands into the startup files.

Check Content

Check run control script modes. # ls -lL /etc/rc* /etc/init.d /lib/svc/method If any run control script has a mode more permissive than 0755, this is a finding.

Fix Text

Ensure all system startup files have mode 0755 or less permissive. Examine the rc files, and all files in the rc1.d (rc2.d, and so on) directories, and in the /etc/init.d and /lib/svc/method directories to ensure they are not world-writable. If they are world-writable, use the chmod command to correct the vulnerability and to research why. Procedure: # chmod go-w <startupfile>
