thinkphp日志泄露

漏洞简介

thinkphp在开启DEBUG的情况下会在Runtime目录下生成日志，虽然Thinkphp官方一再强调生产模式下需要关闭debug，但很多管理员还是忘记关闭。

ThinkPHP3日志目录：

• /Runtime/Logs/
• /App/Runtime/Logs/
• /Application/Runtime/Logs/Admin/
• /Application/Runtime/Logs/Home/
• /Application/Runtime/Logs/
• ...

日志格式为：/App/Runtime/Logs/21_05_17.log

ThinkPHP5日志目录：

• /runtime/log/

日志格式为：/runtime/log/202105/17.log

通过查看日志内容可以发现管理员登录时的SQL语句，进而获取管理员的密码

检测POC

把TP3和TP5的检测POC写在一起了，正则匹配出密码的这一步没有做，因为不同网站的查询SQL语句不一样，很难做到一个正则匹配完全。

常规的密码正则匹配如下

password_pattern = r"`username` = '{}' \) AND \( `password` = '(.*?)'".format(username)

基于pocsuite3的日志检测POC（检测是否有本月内的日志）
