Description |
---|
The umask controls the default access mode assigned to newly created files. A umask of 077 limits new files to mode 700 or less permissive. Although umask is often represented as a 4-digit octal number, the first digit representing special access modes is typically ignored or required to be 0. |

Determine if there are any crontabs by viewing a long listing of the directory. If there are crontabs, examine them to determine what cron jobs exist. Check for any programs specifying an umask more permissive than 077: Procedure: # ls -lL /var/spool/cron /var/spool/cron/tabs # ls -lL /etc/crontab /etc/cron.{d,daily,hourly,monthly,weekly} or # ls -lL /etc/cron.*|grep -v deny # cat # grep umask If there are no cron jobs present, this vulnerability is not applicable. If any cron job contains an umask more permissive than 077, this is a finding. |
