Vulnerability discussion

World writable files could be modified accidentally or maliciously to compromise system integrity.

Check content

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 text

Remove the world writable permission from programs or scripts executed by run control scripts. Procedure: # chmod o-w

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
