我的任务是发现一个用于报告的ODBC DSN，其中密码与用户匹配，并且用户属于数据库服务器管理组。

因此，任何具有此ODBC DSN的PC都可以使用任何ODBC兼容工具通过报表用户读取/更改所有数据(甚至更糟)。不需要授权，而且身份验证非常弱。

我在一家公立医院工作，这个软件几乎安装在该州每家政府医院的每一台电脑上，数据库服务器包含各种敏感的医疗数据(完整的患者详细信息、实验室测试结果等)。

最糟糕的是，我们悄无声息地报告了安全漏洞，然后正式报告，但在我继续在那里工作的2年里，它仍然没有修复，那已经是5年前的事了。

测试一些银行柜员软件后，我打电话给技术部安排了一次拨号IP会话。“您想连接到哪个系统，生产系统还是测试系统?”

真实的故事。

我见过缓冲区溢出，可以(理论上)通过传真输出。

有一个自动的文件路由过程，它将传真作为输入，对它们进行OCR并提取一些信息，然后在此基础上进行LDAP搜索，等等。 不知道这是不是“最糟糕的”，但肯定让我笑了。

前一段时间，JPG图像加载库的窗口存在安全漏洞。被电子邮件中的图像感染。消

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!

I was going to earn my credit with the supervisor for my quite advanced graphics program at a SunOS / Solaris with instant messaging enabled where with zephyr.vars or whatever it was called you could make an image appear on your listed friend's screen like if you alowed me I could just send you an image that appeared on your display. While I was demoing the program I had written so that the supervisor could give me credit for it, one of my friends sitting close or in the next room made the photo big-mama.xxx appear on my screen. There was never any discussion or penalty because of the incident and I got credit for the project that for ½ second seemed like it was programmed to display big-mama.xxx instead of solving the problem. (Earlier) I updated perl scripts and waited for sysadmin to reflect the changes to ouside the FW. Then the database was gone and it was not a bug it was a feature since the data was stored with the source and therefore updating the source blanked the persistence.
