Yet, version 8 implements an exceptional, and powerful, SQL standard feature - Roles - which alleviates one of the more redundant areas of the entire process: assigning privileges to a user. In older versions of MySQL, a multiple-user environment is established in a somewhat monotonous and repetitive manner. You can imagine (I know I do) just how difficult a task managing multiple users or groups of users within a database ecosystem is. Buyers of a service need to see their order and payment history….DBA’s need ‘root’ or similar type privileges to run the show….Developers require a slew of permissions and privileges to carry out their work….Analyst need ‘ read access‘, to garner information and insight via querying tables….However, some tables and data should be strictly off-limits (E.g., system tables). While each user does need to access the database at some level, those permissions are not all created equal.įor instance, clients and customers need access to their ‘related user account’ data, but even that should be monitored with some level of control. Database developers, administrators, analyst, etc… - Those maintaining, working with or monitoring the database infrastructure.Application, service, or program users - basically customers or clients using a service.In terms of database systems, I generally think of them in two distinct groups: SELECT table_schema, table_name FROM information_schema.Database Security is important to any MySQL setup. SELECT table_schema,table_name FROM information_schema.tables WHERE table_schema != ‘mysql’ AND table_schema != ‘information_schema’ SELECT table_schema, table_name, column_name FROM information_lumns WHERE table_schema != ‘mysql’ AND table_schema != ‘information_schema’ SELECT schema_name FROM information_schema.schemata - for MySQL >= v5.0 SELECT grantee, privilege_type, is_grantable FROM information_er_privileges WHERE privilege_type = ‘SUPER’ SELECT host, user FROM er WHERE Super_priv = ‘Y’ # priv SELECT grantee, privilege_type, is_grantable FROM information_er_privileges - list user privsSELECT host, user, Select_priv, Insert_priv, Update_priv, Delete_priv, Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv, File_priv, Grant_priv, References_priv, Index_priv, Alter_priv, Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv, Execute_priv, Repl_slave_priv, Repl_client_priv FROM er - priv, list user privsSELECT grantee, table_schema, privilege_type FROM information_schema.schema_privileges - list privs on databases (schemas)SELECT table_schema, table_name, column_name, privilege_type FROM information_lumn_privileges - list privs on columns John the Ripper will crack MySQL password hashes. SELECT host, user, password FROM er - priv These are marked with “– priv” at the end of the query. Some of the queries in the table below can only be run by an admin. I’m not planning to write one for MS Access, but there’s a great MS Access Cheat Sheet here. The complete list of SQL Injection Cheat Sheets I’m working is: This helps to highlight any features which are lacking for each database, and enumeration techniques that don’t apply and also areas that I haven’t got round to researching yet. In this series, I’ve endevoured to tabulate the data to make it easier to read and to use the same table for for each database backend. This post is part of a series of SQL Injection Cheat Sheets. Some useful syntax reminders for SQL Injection into MySQL databases…
