这是很久以前的事了……但DEC的VAX系统过去是随账户一起发货的:

系统登录: 密码:经理

而且 登录:字段 服务密码:

大多数系统管理员都知道SYSTEM帐户，并且大多数(但不是全部)会更改它。然而，并不是所有人都知道FIELD帐户也有SYSTEM特权。

The worst security hole I've seen was from a (very very bad) hosting company. And even worse it was just some months ago (summer 2010)! You had to first connect to your hosting package control panel (you needed valid credentials). Once logged in all you had to change was the id GET token from the URL and voilà, you're in the control panel of another user! You have access (save/edit/delete) to emails, files, databases. The ids were sequential so you only have to do +1 and you're in the next account. I hope someone have been fired for this!

这是我和他们一起经历过的众多WTF之一!幸运的是，我不是他们的顾客!

我继承了一个客户项目来照看:一个ASP。网项目 (构建于1.1)，其中50%是编译DLL(没有编译DLL) 源代码)和50%的JIT编译后代码。

整个网站应该只对会员开放——除了 原来的开发人员已经建立了一个后门:只需提交 用空白的用户名和密码登录表单，你就会 找到自己作为一个秘密的超级管理员登录:做 什么都看，什么都看。

您猜对了:所有的身份验证代码都被隐藏了 在预编译的DLL中。最糟糕的是当我 被告知“它不在bug列表中，那么客户端呢? 不会付钱，所以离开它”。我照做了，现在还在直播 今天。

我听说，当你以电子方式提交申报表时，Turbo Tax曾经以纯文本文件发送你的SSN。这似乎不是个好主意。

我还知道一家公司将信用卡信息存储在桌面上的纯文本CSV文件中。然后通过FTP发送到支付网关....

Right at the start of the .com era, I was working for a large retailer overseas. We watched with great interest as our competitors launched an online store months before us. Of course, we went to try it out... and quickly realized that our shopping carts were getting mixed up. After playing with the query string a bit, we realized we could hijack each other's sessions. With good timing, you could change the delivery address but leave the payment method alone... all that after having filled the cart with your favorite items.

我不知道这是不是最糟糕的，因为我见过一些非常糟糕的，但是:

几年前，我工作的地方引进了一个叫做FOCUS的系统。不知道它还在不在。它非常适合做报告，我们开发并教了大约一千两个非It人员如何生成他们自己的报告。非常方便。他们可以做基本的报告，一些人可以做中等难度的工作，IT可以帮助处理较难的工作。

所有用于报告的数据都被定期复制到FOCUS自己格式的影子数据库中。对于更敏感的数据，我们设置安全选项，加密数据。一切都很好。

So, one day my boss calls me in, and we've lost the password to one of the sensitive databases. It's going to be hard to reproduce the data in this case, so he asks me to see if I can break the security. I had no experience as a hacker, so it took me about 5 or 6 hours to hand him the password. I started by creating some test files, and encrypting them with different passwords. I found that changing one character in the password would change two bytes in the encrypted file, specifically, the high nybble of one byte, and the low nybble of another byte. Hmmmm, says I. Sure enough, they stored the password somewhere in the first 80 bytes of the encrypted, but obfuscated the password by splitting the bytes into nybbles, and storing them in predictable places.

不久之后，我们就编写了一个REXX脚本，该脚本在VM/CMS系统下运行，可以告诉我们任何加密数据库的密码。

那是很久以前的事了——在90年代初，我相信他们已经解决了这个问题。嗯，非常确定。
