漏洞出现在:

method_4 :

private void method_4()
    {
///如果用户是 admin 或者 提交的current_username 和当前string_1 一样  string_1 是你登录的SESSION 所以需要登录
      if ((!(this.string_1 != this.Request.Form["current_username"]) ? 1 : (!(this.string_1 != "admin") ? 1 : 0)) == 0)

      this.Response.End();
    }

this.method_7 :

  private void method_7()
    {
      if (!(this.author != ""))//。。。。。
        return;
//发送消息 调用了this.method_8() 继续跟
      new SendMessage(this.int_1).SendEmail(this.method_8(), "", "", this.Request.Form["fb_title"], this.Request.Form["reply"]);
    }

this.method_8:

private string method_8()
    {
      string str = "";//----------------OK这里直接进入SQL语句,没任何妨碍,但是没有回显。
      OleDbDataReader oleDbDataReader = new OleDbCommand("select email from pa_member where username='" + this.author + "'", this.oleDbConnection_0).ExecuteReader();
      if (oleDbDataReader.Read())
        str = oleDbDataReader["email"].ToString();
      oleDbDataReader.Close();
      return str;
    }

证明

利用
SQL SERVER 都无所谓回显不会显 各种语句可以搞。
说说 ACCESS版本的
ACCESS 没有延迟的函数,但后来找了资料,也是可以注入延迟的

1.先注册后,登录。
2.burp suite 抓好COOKIE
3.提交 Payload

POST /e/member/state.aspx?table=pa_member&detailid=2&workid=1&s=1

提交条件假

提交条件真
