最不可原谅的安全漏洞，不幸的是，一个非常常见和容易找到的漏洞，是谷歌黑客。举个例子:

http://www.google.com/search?q=inurl%3Aselect+inurl%3A%2520+inurl%3Afrom+inurl%3Awhere

令人惊讶的是，互联网上有多少页面，特别是政府网站，通过查询字符串传递SQL查询。这是最糟糕的SQL注入形式，查找易受攻击的站点毫不费力。

经过一些小的调整，我已经能够找到未受保护的phpMyAdmin安装，未受保护的MySQL安装，查询包含用户名和密码的字符串，等等。

最糟糕的安全漏洞是使用ie浏览器的选项来记住你的密码。人们没有意识到的是，像Nirsoft这样的工具可以泄露你所有的密码。

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.

在这里根据记忆来解释，但它很接近……

<form action="secretpage.html" id="authentication"          
      onsubmit="return document.forms.authentication.password.value == 's3cr3t'">
    Enter password: <input type="password" name="password"><br>
    <input type="submit" name="Login" >
</form>

我认识的一个家伙用这个来保护他网站的“私人区域”。起初，他不愿意相信我，甚至他的浏览器都有这个不可靠的“查看源代码”功能。

在我工作的一个网站上，他们使用用户名和密码作为组合主键。用户名自动是您的姓，不需要唯一。

这就只剩下一件独一无二的事情了…

整个经典ASP购物车“Comersus”。整个事情是意大利面条代码的混乱，所有的SQL语句都是成熟的SQL注入，因为没有做任何过滤。可悲的是，我不幸地处理了近两年的“申请”，这绝对是一场噩梦!
