Spam email server security

one of my clients has been accused of spamming. I am sure he has not done it. I looked at his server and found these files under his CGI directory.

cgiecho.is.exploitable
Cgimail

I have never seen this file. does anyone have any info on this?

some one has used his account to send mass email to AOL email addresses.
What do you think they could have used to do this?
