Command injection with no spaces

 Folks,

 We came across an interesting bug in a web system where we could execute
any system command (on AIX) but we could not enter any spaces in the
command and we would only get the last line of STDOUT.

 Has anyone else come across anything like this?

 The most we were able to do was cat the last line from system files and
determine if a directory existed.

 Cheers,

 Matt
