Ensure 'allow-suspicious-udfs' is Set to 'OFF'

中级别 2自动化mysql

说明

This option prevents attaching arbitrary shared library functions as user-defined functions by checking for at least one corresponding method named _init, _deinit, _reset, _clear, or _add. Counts allow-suspicious-udfs settings in the server option groups (my_print_defaults mysqld) and on the running server command line.

检查方式

审计方法: Shell 命令

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"||$1=="mariadbd"' | tr ' ' '\n'; } | grep -Eic '^--allow[-_]suspicious[-_]udfs(=(1|on|true|yes))?$' ); echo "$n"

预期输出: 0

修复方式

修复方法: 操作指南或基础设施补丁

Remove allow-suspicious-udfs from the MySQL option files and from the server start-up command line, then restart.
