Natas6 Writeup(PHP Include)

Natas6:

该题提供了php源码,点击查看分析,发现调用了includes/secret.inc页面,在输入一个变量secret后,如果和includes/secret.inc中 预设的secret相同,则输出密码。

include "includes/secret.inc";

if(array_key_exists("submit", $_POST)) {
	if($secret == $_POST['secret']) {
		print "Access granted. The password for natas7 is <censored>";
	} else {
		print "Wrong secret";
	}
}

尝试访问该页面—http://natas6.natas.labs.overthewire.org/includes/secret.inc,在其源码中发现预设字符——"FOEIUWGHFEEUHOFUOIU",将该字符输入到之前的表单查询中,得到flag。
