<p>错误的配置文件示例（原本的目的是为了让http的请求跳转到https上）：</p>
<pre class="prettyprint linenums prettyprinted" style=""><ol class="linenums"><li class="L0"><code><span class="pln">location </span><span class="pun">/</span><span class="pln"> </span><span class="pun">{</span></code></li><li class="L1"><code><span class="pln">    </span><span class="kwd">return</span><span class="pln"> </span><span class="lit">302</span><span class="pln"> https</span><span class="pun">:</span><span class="com">//$host$uri;</span></code></li><li class="L2"><code><span class="pun">}</span></code></li></ol></pre><p>Payload: <code>http://url/%0a%0dSet-Cookie:%20a=1</code>，可注入Set-Cookie头。</p>
<p>利用Payload: <code>http://url/%0D%0ASet-Cookie:%20a=1%0d%0a%0d%0a&lt;img src=1 οnerrοr=alert(/xss/)&gt;</code> ,可构造一个xss漏洞：</p>

<h3 id="h3-2-"><a name="2、    目录穿越漏洞" class="reference-link"></a><span class="header-link octicon octicon-link"></span>2、    目录穿越漏洞</h3><p>Nginx在配置别名（Alias）的时候，如果忘记加/，将造成一个目录穿越漏洞。</p>
<p>错误的配置文件示例（原本的目的是为了让用户访问到/home/目录下的文件）：</p>
<pre class="prettyprint linenums prettyprinted" style=""><ol class="linenums"><li class="L0"><code><span class="pln">location </span><span class="pun">/</span><span class="pln">files </span><span class="pun">{</span></code></li><li class="L1"><code><span class="pln">    </span><span class="kwd">alias</span><span class="pln"> </span><span class="pun">/</span><span class="pln">home</span><span class="pun">/;</span></code></li><li class="L2"><code><span class="pun">}</span></code></li></ol></pre><p>Payload: <a href="http://URL/files../">http://URL/files../</a> ，成功穿越到根目录：</p>

<h3 id="h3-3-add_header-"><a name="3、    add_header被覆盖" class="reference-link"></a><span class="header-link octicon octicon-link"></span>3、    add_header被覆盖</h3><p>Nginx配置文件子块（server、location、if）中的add_header，将会覆盖父块中的add_header添加的HTTP头，造成一些安全隐患。</p>
<p>如下列代码，整站（父块中）添加了CSP头：</p>
<pre class="prettyprint linenums prettyprinted" style=""><ol class="linenums"><li class="L0"><code><span class="pln">add_header </span><span class="typ">Content</span><span class="pun">-</span><span class="typ">Security</span><span class="pun">-</span><span class="typ">Policy</span><span class="pln"> </span><span class="str">"default-src 'self'"</span><span class="pun">;</span></code></li><li class="L1"><code><span class="pln">add_header X</span><span class="pun">-</span><span class="typ">Frame</span><span class="pun">-</span><span class="typ">Options</span><span class="pln"> DENY</span><span class="pun">;</span></code></li><li class="L2"><code></code></li><li class="L3"><code><span class="pln">location </span><span class="pun">=</span><span class="pln"> </span><span class="pun">/</span><span class="pln">test1 </span><span class="pun">{</span></code></li><li class="L4"><code><span class="pln">    rewrite </span><span class="pun">^(.*)</span><span class="pln">$ </span><span class="pun">/</span><span class="pln">xss</span><span class="pun">.</span><span class="pln">html </span><span class="kwd">break</span><span class="pun">;</span></code></li><li class="L5"><code><span class="pun">}</span></code></li><li class="L6"><code><span class="pln">location </span><span class="pun">=</span><span class="pln"> </span><span class="pun">/</span><span class="pln">test2 </span><span class="pun">{</span></code></li><li class="L7"><code><span class="pln">    add_header X</span><span class="pun">-</span><span class="typ">Content</span><span class="pun">-</span><span class="typ">Type</span><span class="pun">-</span><span class="typ">Options</span><span class="pln"> nosniff</span><span class="pun">;</span></code></li><li class="L8"><code><span class="pln">    rewrite </span><span class="pun">^(.*)</span><span class="pln">$ </span><span class="pun">/</span><span class="pln">xss</span><span class="pun">.</span><span class="pln">html </span><span class="kwd">break</span><span class="pun">;</span></code></li><li class="L9"><code><span class="pun">}</span></code></li></ol></pre><p>但/test2的location中又添加了X-Content-Type-Options头，导致父块中的add_header全部失效：</p>

<p>XSS可被触发：</p>

<p>也可配合文件上传来getshell。此处不再演示。</p>
