[原文]SQL injection vulnerability in Lyris ListManager 5.0 through 8.9a allows remote attackers to execute arbitrary SQL commands via SQL code after a numeric argument to a /read/attachment URL.


[CNNVD]Lyris Listmanager多个SQL注入漏洞(CNNVD-200512-186)

        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。

Lyris ListManager Read Message Attachment SQL Injection
Remote / Network Access Information Disclosure, Input Manipulation
Loss of Confidentiality, Loss of Integrity
Exploit Public

- 漏洞描述

Lyris ListManager contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the read message attachment function not properly sanitizing user-supplied input to the attachment URL. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
