Ensure 'mysqld' is Not Started With '--skip-grant-tables'
CriticalLevel 1Automatedmysql
Description
This option causes mysqld to start without using the privilege system. Counts enabled skip-grant-tables settings in the server option groups and on the running server command line.
How it is checked
Audit method: Shell command
shell
c=$(my_print_defaults mysqld 2>/dev/null) || exit 1; p=$(ps -eo comm=,args= 2>/dev/null) || exit 1; n=$( { printf '%s\n' "$c"; printf '%s\n' "$p" | awk '$1=="mysqld"||$1=="mariadbd"' | tr ' ' '\n'; } | grep -Eic '^--skip[-_]grant[-_]tables(=(1|on|true|yes))?$' ); echo "$n"- Expected output
0
How it is fixed
Fix method: Guidance or infrastructure patch
Remove skip-grant-tables (and skip_grant_tables) from the option files or set skip-grant-tables = FALSE, remove it from the start-up command line, and restart MySQL.
