You might want to look at http://packetstormsecurity.nl/UNIX/misc/asc.c, which can generate ascii shellcode from binary shellcode. Depending on the environment, a return to a libc jmp register may be feasible to you. Potentially, http://www.phrack.org/show.php?p=59&a=7 may be interesting to you, wrt jump codes. Then again, it may be straight forward ;)
Hi! This is my first post and I'm looking for some documentation. A friend of mine has produced a segfault with malloc vulnerability on an application. We would like to produce something more interesting. The field overflowed can accept only characters between 0 and 128. Any other character is replaced with a whitespace. Can we inject shellcode with only this characters avaible? Can you suggest me documentation about shellcode writing? Thanks a lot JohnnyRun -- -------------------------------
