“网络编程安全101”风格的最大错误是招聘机构的搜索页面提供了“下一页”链接，这只是获取更多工作列表的SQL语句。您可以轻松地将此URL更改为任何其他SQL语句，包括“drop table X”。如果你这么做了，他们的整个网站都会完蛋。

默认登录凭据，特别是当是admin/root和密码时。

1-800 dominos will give unlisted address's related to any target phone number. When prompted if you are calling about the phone number you called from select no. The system will prompt you for a new phone number, the system will then read back to you the name and address that's associated to this phone number. Enter in your target's phone number and you now have their name and address. This is pretty common with automated ordering systems and if dominos has fixed this there are literally hundreds more.

public class AuthenticationServlet extends HttpServlet
{
    private String userName;
    private String password;

    protected doPost(HttpServletRequest req, HttpServletResponse resp)
           throws ServletException, IOException
    {
        userName = request.getParameter("userName");
        password = request.getParameter("password");
        authenticateUser(userName,password);
        ......
    }
}

显然，正如有人在自动化负载测试中发现的那样，单例和缺乏同步会导致安全问题。

作为一个以应用程序安全顾问为生的人，有很多常见的问题让你通过一些东西来管理网站。但真正酷的是你可以买到价值一百万美元的袜子。

这是我的一个朋友的工作，但它的真实情况是，某个现在非常流行的在线图书(和其他所有东西)商店的商品价格被存储在HTML本身作为一个隐藏字段。在早期，这个漏洞困扰了许多在线商店，他们刚刚开始了解网络。几乎没有安全意识，谁会下载HTML，编辑隐藏字段，然后重新提交订单呢?

当然，我们把价格改为0，并订购了100万双袜子。你也可以改变价格为负，但这样做使他们的后端计费软件缓冲区溢出结束交易的一部分。

如果我可以选择另一个，那就是web应用程序中的路径规范化问题。能够执行foo.com?file=../../../ etc/passwd真是太棒了
