BUGTRAQ ID: 15787

Lyris ListManager是用于管理邮件列表，创建邮件、新闻组和讨论组的软件解决方案。

ListManager中用于读取消息附件的函数中存在SQL注入漏洞，远程攻击者可能利用此漏洞在主机上执行任意命令。

攻击者可以通过请求以下URL对后端数据库执行任意命令：
/read/attachment/1;DELETE FROM TABLENAME;--/3

此外，orderby参数中也存在多个SQL注入漏洞。攻击者可以向web界面中所显示大部分项提供SQL "ORDER BY"列。处理这个字段的代码检查了空格和tab字符，但支持的数据库允许其他形式的空位。如果用户在使用MSSQL/MSDE后端的话，攻击者就可以将换行字符用作空位并在cmd.exe字符串中用ASCII 0xFF替换空格来访问xp_cmdshell存储的过程。

This module exploits a SQL injection flaw in the Lyris ListManager
software for Microsoft SQL Server. This flaw allows for arbitrary commands
to be executed with administrative privileges by calling the xp_cmdshell
stored procedure. Additionally, a window of opportunity is opened during the
ListManager for MSDE install process; the 'sa' account is set to the password 'lminstall'
for a 5-10 minute period. After the installer finishes, the password is
permanently set to 'lyris' followed by the process ID of the installer (a 1-5 digit number).
