其中poc使用echo + md5的payload检测。当页面中返回这些值的时候判断漏洞存在,会导致一些组件误报。测试代码:

<?php
echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo file_get_contents("php://input");
?>

误报情况:

命令执行用expr或者set等命令误报会更低

代码执行直接计算md5误报率更低,echo md5("xxx");

已经有模块来处理echo的误报了,0.6重构时量太大忘记了几个,0.7中已经把echo全部加入误报处理中
感谢建议,该问题已在0.7中解决,4月初发布
