Check the permissions on the files or scripts executed from system startup scripts to see if they are world-writable.
Create a list of all potential run command level scripts.
# ls -l /etc/init.d/* | tr '\011' ' ' | tr -s ' ' | cut -f 9,9 -d " "
OR
# ls -l /sbin/init.d/* | tr '\011' ' ' | tr -s ' ' | cut -f 9,9 -d " "

Create a list of world writeable files.
# find / -perm -002 -type f >> worldWriteableFileList

Determine if any of the world writeable files in worldWriteableFileList are called from the run command level scripts. Note: Depending upon the number of scripts vs world writeable files, it may be easier to inspect the scripts manually.
# more `ls -l /etc/init.d/* | tr '\011' ' ' | tr -s ' ' | cut -f 9,9 -d " "`
OR
# more `ls -l /sbin/init.d/* | tr '\011' ' ' | tr -s ' ' | cut -f 9,9 -d " "`

If any system startup script executes any file or script that is world-writable, this is a finding.

Fix Text (F-1064r2_fix)
Remove the world-writable permission from programs or scripts executed by run control scripts. Procedure: # chmod o-w
