Joomla! VirtueMart component <= 2.0.22a - SQL Injection
------------------------------------------------------------
 
==概述==
- 下载地址: http://www.virtuemart.net/
-  影响版本: All versions between 2.0.8 and 2.0.22a are vulnerable.
-  漏洞发现: Matias Fontanini
 
== 缺陷 ==
The vulnerability is located in the "user" controller, "removeAddressST" 
task. The "virtuemart_userinfo_id" parameter is not properly sanitized 
before being used in the "DELETE" query performed in it, allowing the 
execution of arbitrary SQL queries.
 
In order to exploit the vulnerability, an attacker must be authenticated 
as a customer in the application. However, since the system allows free 
account registration, this is not a problem.
 
== 测试证明  ==
The following example URL uses the MySQL "sleep" function through the 
injection:
 
http://example.com/index.php?option=com_virtuemart&view=user&task=removeAddressST&virtuemart_userinfo_id=16%22%20and%20sleep(10)%20and%20%22%22%3D%22
 
== 解决方案 ==

升级到新版 2.0.22b
