| Description |
|---|
| World writable files could be modified accidentally or maliciously to compromise system integrity. |
| ℹ️ Check |
|---|
| 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/* /etc/rc* | tr '\011' ' ' | tr -s ' ' | cut -f 9,9 -d " " Create a list of world writable files. # find / -perm -002 -type f >> WorldWritableFileList Determine if any of the world writeable files in "WorldWritableFileList" are called from the run command level scripts. Note: Depending upon the number of scripts vs. world writable files, it may be easier to inspect the scripts manually. # more `ls -l /etc/init.d/* /etc/rc* | 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 |
|---|
| Remove the world writable permission from programs or scripts executed by run control scripts. Procedure: # chmod o-w <program or script executed from run control script> |
