This is not entirely true.  The apache server would have to be running as 
root which if exploited then allows the malicious code to do things as 
root.  AFAIK, the Apache webserver by default runs as the user 'nobody' 
which then the malicious code may only be run as that unprivileged user.  I 
admit that some admin run the server as root (not wise...of course.  Even 
the configs for the server state its not wise) which in this case I could 
see where said virus could cause harm.

Including me.  They are unethical.
