// Lsof is an open file management utility included with many linux distributions. When run setuid root or setgid kmem, it is subject to a buffer overflow that can lead to regular users gaining root priveleges.

* Sekure SDI (Brazilian Information Security Team)
|
|
* lsof local exploit for linux
|
|
* by c0nd0r <condor@sekure.org>
|
|
*
|
|
* Security problem found by HERT. (www.hert.org)
|
|
*
|
|
* -> This little tool will bring you a suid or sgid shell owned by lsof
|
|
* user (root|kmem usually) at /tmp directory (/tmp/sh).
|
|
*
|
|
* -----------------------------------------------------------------------
|
|
* Code explanation: We've used a unsual technique here.
|
|
* The buffer allocated was too small for the standard expl, so we did a
|
|
* little trick, by overflowing with 'A' till reaching the ret address and
|
|
* then we've filled with NOP and the shellcode just after the modified
|
|
* ret address. So we have a different exploit architeture:
|
|
* [garbage][eip modified][lotsa NOP's][shellcode]
|
|
* That's why we need a bigger offset.
|
|
* -----------------------------------------------------------------------
|
|
*
|
|
* usage ( needa have a little brain):
|
|
* ./SDI-lsof <offset> (between 373-505)
