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.

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。

一个“安全”的网站，每个页面都是加密的，但登录页面!

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

我将分享一个我创造的。种。

多年、多年、多年以前，我工作的公司需要在他们的ASP网站上建立索引。所以我去设置索引服务器，排除了一些管理目录，一切都很好。

然而，我不知道有人给了一个销售人员ftp访问网络服务器，这样他就可以在家工作，这是拨号的日子，这是他交换文件的最简单的方式....他开始上传东西，包括详细说明我们服务....标记的文档当人们搜索“成本”时，索引服务器就会索引并开始提供服务。

记住，孩子们，白名单不是黑名单。
