2007年，一家相当大的机构的国防部网站出现了错误配置，导致IIS web服务器提供原始代码，主页中有硬编码的用户名/密码和数据库服务器信息。幸运的是，它很快就被抓住了，但我确实目睹了它，这非常令人震惊。不用说，他们的网站被网络工程师关闭了，直到开发人员修复了糟糕的代码。

在我以前的学校，他们把用户密码以明文形式存储在cookie中。

这本身就很可怕，但更糟糕的是，他们把它们储存在饼干里供*.大学。当然，现在所有学生和员工的页面都在university.edu.au/~user这样的网站上。

<?php

var_dump($_COOKIE); // oops.

在登录时，有一个隐藏的字段，让“网站管理员”选择成功和失败时要包含的文件。

是的，/etc/password工作了。

或者在“log”目录中，有order-xxx。order-xxx.txt包含卡号，包括检查号和验证日期。

UNIX文本登录屏幕是如此容易复制…：）

About 3 years ago I built a site for a somewhat large non-profit organization in our state. When it came time to deploy the application to their web host server, I noticed an odd file named "cc.txt" or something obvious like that in their public site. It was under their web root, was getting served, and was a csv file of all their donor's names, addresses, credit card numbers, expiration dates, and CVV/CVC codes. I cannot count the number of times I brought the issue up - first to my boss, then our company accountant, the client's IT director, finally the client's President. That was 3 years ago. The file is still being served, it can even be googled. And it's been updated. I tend not to respond to their donation solicitations when I get them.

对我来说，最糟糕的，最可怕的，最危险的，犯罪的疏忽，但在彻底破坏整个系统的安全方面，奇怪的优雅总是来自the Daily WTF:

客户端PHP

function saveform()
{
  var firstName = escapeSql(mainForm.elements.txtFirstName.value);
  var lastName = escapeSql(mainForm.elements.txtLastName.value);
  /* ... */
  var offerCode = escapeSql(mainForm.elements.txtOfferCode.value);

  var code =
  '  $cn = mssql_connect($DB_SERVER, $DB_USERNAME, $DB_PASSWORD)           ' +

  '                                                                        ' +
  '  /* ... */                                                             ' +

  '  mssql_close($cn);                                                     ';

  execPhp(code);
}

就盯着它看一分钟。想想你所能做的一切。女士们先生们，这是洛夫克拉夫特的杰作。
