找source file;问题:老是扫不出来东西怎么办 emm
扫描出文件index.php.bak
<?php
include_once "flag.php";
if(isset($_GET['key'])) {
$key = $_GET['key'];
if(!is_numeric($key)) {
exit("Just num!");
}
$key = intval($key);
// intval — Get the integer value of a variable
$str = "123ffwsfwefwf24r2f32ir23jrw923rskfjwtsw54w3";
if($key == $str) { // ** 弱类型比较
echo $flag;
}
}
else {
echo "Try to find out source file!";
}
?>
弱类型比较 => payload = url/index.php?key=123 => 得到flag

字典老是不是非常nice 以至于扫不出想要的结果 => 非常十分急需解决的问题!!
