Portable shell-exploit for buffer-overflow bugs



Hello str0ke,

I reviewed the exploits listed. Yes, all of them use the shell but they
exploit trivially shell-exploitable bugs (like race conditions, ld-preload,
etc) or include other "external" programs (like cc, perl, etc) or assume
Linux/bash as well as other more or less recent environments.

The nearest exploit to what I was looking for (buffer overflow exploit in
shell-scripting) is:
http://milw0rm.com/exploits/18

But it lacks compatibility. For instance, "echo" command is very variable,
depending on OS/Shell version. I've uploaded a proof of concept which I
wrote some time ago, showing my approach, to:
http://www.rs-labs.com/exploitsntools/rs_aix_host.sh
(~6 KB)

It may not be perfect but my goal was to make it work in a very old minimal
Unix environment (the exploit yields local root on AIX 4.1.4.0, abusing a
known and ancient bug: ~ 10 years old!) and at the same time compatible
with some recent systems like Linux/bash (logically, the vulnerability is
not present in such systems, I'm referring to the skel of the exploit).

Feedback would be appreciated.

PS: I'm cc'ing some lists where this post could suit. Moderators should decide.

Cheers,
-Roman

How goes it Roman,

Which other "curious" exploits in shell do you know of?

Attached is a list of the known exploits that are in shell, some call
other languages some don't.
