(in version v1 r3)
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. # cd /etc # find rc* -ls 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, all files in the rc1.d (rc2.d, and so on) directories, and in the /etc/init.d directory to ensure they are not world-writable. If the files are world-writable, use the chmod command to correct the vulnerability and research why they are world-writable. Procedure: # chmod 755 startupfile Document all changes.
