Java - XSS - HTML编码 - 字符实体引用 vs数字实体引用
原标题:Java - XSS - HTML encoding - Character entity reference vs. Numeric entity reference

我们一直在寻找方法将我们的JSP页面进行HTML编码,以防XSS攻击。

OWASP网站显示如何在Java中执行HTML实体编码

这篇文章讲述了实体编码"大五码"的问题,也就是指五个汉字编码标准。

  21          {"#39", new Integer(39)}, //   - apostrophe
  22          {"quot", new Integer(34)}, // " - double-quote
  23          {"amp", new Integer(38)}, // & - ampersand
  24          {"lt", new Integer(60)}, // < - less-than
  25          {"gt", new Integer(62)}, // > - greater-than

i.e.

<script>

被编码为

  &lt;script&gt;

但是文章中包含的Java代码示例使用数字参考编码,即...

<script></script>

被编码为

 &#60;script&#62;&#60;&#47;script&#62;

使用字符引用而不是实体引用是否有理由?哪个更好,为什么?

最佳回答

就防止XSS而言,它们是相同的。唯一真正的实际区别是可读性和大小。
