最近，我遇到了一些用户请求 PHP 页面的 404 错误。

URL 的范围围绕cgi-bin和php版本，例如/cgi-bin/php4. 作为请求的一部分，还有一些查询字符串。

%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

这意味着：

-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

我没有暴露cgi-bin或php暴露文件夹，所以我并不太担心这些请求，但我很好奇他们正在寻找什么来确保我得到修补。
