作者: zclzhao 时间: 2009-11-7 12:20 标题: Symantec Altiris ConsoleUtilities ActiveX控件缓冲区溢出漏洞

影响版本:
Altiris Deployment Solution 6.x
Altiris Notification Server 6.x
Symantec Altiris ConsoleUtilities ActiveX Control 6.x
Symantec Management Platform 7.x漏洞描述:
Bugraq ID: 36698
CVE ID：CVE-2009-3031

Symantec Altiris Deployment Solution是自动化的操作系统部署解决方案，用于从统一的位置部署和管理服务器、桌面和笔记本等。
在初次访问Altiris Deployment Solution等产品管理服务器的管理WEB站点时会安装一个ActiveX控件(AeXNSConsoleUtilities.dll)，此函数"BrowseAndSaveFile"存在一个基于栈的缓冲区溢出：
Name:          ConsoleUtilities Class
Vendor:          Altiris, Inc.
Type:          ActiveX-Steuerelement
Version:       6.0.0.1846
GUID:          {B44D252D-98FC-4D5C-948C-BE868392A004}
File:          AeXNSConsoleUtilities.dll
Folder:          C:\WINDOWS\system32
提交超长的字符串作为"BrowseAndSaveFile"函数的参数，可触发基于栈的缓冲区溢出，攻击者构建恶意WEB页，诱使用户解析可以应用程序权限执行任意指令。<*参考
