上面的是动易的上传代码，从上面分析，我们可以看到，它明显存在着上传漏洞。重要的漏洞代
码在于这一句
FileExt=lcase(ofile.FileExt) '判断扩展名
arrUpFileType=split(UpFileType, "| ")
for i=0 to ubound(arrUpFileType)
if FileExt=trim(arrUpFileType(i)) then
EnableUpload=true
exit for
end if

next
if FileExt= "asp " or FileExt= "asa " or FileExt= "aspx " or FileExt= "cer " or FileExt= "cdx " then
EnableUpload=false

[解决办法]
strFileName=year(dtNow) & right( "0 " & month(dtNow),2) & right( "0 " & day(dtNow),2) & right( "0 " & hour(dtNow),2) & right( "0 " & minute(dtNow),2) & right( "0 " & second(dtNow),2) & ranNum & ". " & FileExt

这行代码是生成文件名字的，改成提取回来原来的文件名就可以了。
