SemCms （外贸企业网站管理系统）多处漏洞 & SemCms Exp

后台验证：

验证文件：Clkj_Inc\WebOut.asp

<%
if session("username")<>"" then
     Set Rs=server.createobject("adodb.recordset")
     Sql="select * from  clkj_admin  where clkj_password='"&request.cookies("userpas")("upas")&"'"
     Rs.open sql,conn,1,1
     if not (rs.eof and rs.bof) then
         session("username")=request.cookies("username")("uname")
     end if
else
     Response.Write "<script language='javascript'>alert('用户名与密码为空或失效请重新进入!');top.location.href='index.html';</script>"
end if
%>

只需要修改下 cookie username 的值 uname=任意，访问后台 Clkj_Admin\nimda_admin.asp 即可。

文件名前缀很有意思：nimda
