<h1>基于增加复杂逻辑数组混淆的webshell绕过</h1>
|
|||
|
|
<h2 id=toc-0>前言</h2>
|
|||
|
|
<p>最近也是研究起了绕过webshell的学习，说实话绕过waf很不容易，因为对webshell研究少，底层也少，只能目前用逻辑和混淆了</p>
|
|||
|
|
<h2 id=toc-1>webshell检测机制</h2>
|
|||
|
|
<p>如果需要知道如何进攻，那就需要知道该如何去防御，首先就开始慢慢摸索webshell的检测机制了</p>
|
|||
|
|
<h3 id=toc-2>对于全局变量</h3>
|
|||
|
|
<p>我们的全局变量常见的有</p>
|
|||
|
|
<ul>
|
|||
|
|
<li><code>$_GET</code></li>
|
|||
|
|
<li><code>$_POST</code></li>
|
|||
|
|
<li><code>$_COOKIE</code></li>
|
|||
|
|
<li><code>$_REQUEST</code></li>
|
|||
|
|
<li><code>$_SERVER</code> 其中的某些参数可控</li>
|
|||
|
|
<li><code>$_FILE</code></li>
|
|||
|
|
<li>$GLOBALS</li>
|
|||
|
|
</ul>
|
|||
|
|
<p>如果我们使用了这些传入参数，那么webshell检测就会把传入的参数作为source了，被标记，后续会持续跟踪</p>
|
|||
|
|
<h3 id=toc-3>特殊字符</h3>
|
|||
|
|
<p>比如我们执行命令的，system，eval等等这些字符，也会检测参数</p>
|
|||
|
|
<p>总的来说就是污点分析，跟踪</p>
|
|||
|
|
<h3 id=toc-4>绕过方法</h3>
|
|||
|
|
<p><a href=https://zone.huoxian.cn/d/878 target=_blank>https://zone.huoxian.cn/d/878</a></p>
|
|||
|
|
<ol>
|
|||
|
|
<li>SpeedBump, which amplifies the slowdown in normal executions by hundreds of times to the fuzzed execution 在一些非预期的错误处理路径注入延迟原语，影响Fuzz执行速度</li>
|
|||
|
|
<li>BranchTrap, interfering with feedback logic by hiding paths and polluting coverage maps。<br>
|
|||
|
|
插入大量对输入敏感的分支，使得Fuzz处理不得不浪费大量的资源处理这些无用的分支分析中</li>
|
|||
|
|
<li>AntiHybrid, hindering taint-analysis and symbolic execution。<br>
|
|||
|
|
作者将原始程序中的explicit data-flow转换为implicit data-flow，以阻碍污染分析。</li>
|
|||
|
|
</ol>
|
|||
|
|
<h2 id=toc-5>具体案例</h2>
|
|||
|
|
<p>根据一个案例来介绍一下机制</p>
|
|||
|
|
<p>比如今天构造的一个webshell</p>

<p>可以看见逻辑还是比较复杂的，这里简单介绍一下这些函数的作用</p>
|

|
|
<p><strong>array_column</strong></p>
|
|||
|
|
<p>(PHP 5 >= 5.5.0, PHP 7, PHP 8)</p>
|
|||
|
|
<p>array_column — 返回输入数组中指定列的值</p>
|
|||
|
|
<p><strong>array_column()</strong> 返回 <code>array</code> 中键名为 <code>column_key</code> 的一列值。 如果指定了可选参数 <code>index_key</code>，则使用输入数组中 <code>index_key</code> 列的值将作为返回数组中对应值的键。</p>

|
<p>所以我这里就使用这个函数来构造我们的恶意代码，比如system</p>
|
|||
|
|
<p>但是首先只是取出了数组的值，我们还需要使用一些方法把他们拼接在一起</p>
|
|||
|
|
<p><strong>implode</strong></p>
|
|||
|
|
<p>implode — 用字符串连接数组元素</p>
|
|||
|
|
<p>返回一个包含所有数组元素并且顺序相同的字符串， 每个元素之间有 separator 分隔。</p>

<p>那我们这里的思路就是一’‘去拼接在一起</p>
|
|||
|
|
<p>这样我们的恶意字符就构造出来了</p>

<p>然后使用array_push把内容放在数组中</p>
|
|||
|
|
<p>然后再解释一下</p>
|
|||
|
|
<div class=highlight><pre><span></span><span class=x>$$string1['HTTP_ACCEPT'];</span>
|
|||
|
|
</pre></div>
|
|||
|
|
<p>这个就是$_SERVER['HTTP_ACCEPT']</p>
|
|||
|
|
<p>因为我们需要控制参数的内容，而_SERVER中变量还是很多的</p>
|
|||
|
|
<p>PATH 系统环境变量的值，包含了多个目录的路径，用于指定可执行文件的搜索路径。<br>

|
|||
|
|
REQUEST_SCHEME 请求使用的协议。<br>
|
|||
|
|
DOCUMENT_ROOT 当前脚本的文档根目录。<br>
|
|||
|
|
REMOTE_ADDR 客户端的IP地址。<br>
|
|||
|
|
SERVER_PORT 服务器监听的端口号。<br>
|
|||
|
|
SERVER_ADDR 服务器的IP地址。<br>
|
|||
|

HTTP_SEC_FETCH_SITE 请求中的Fetch请求站点。<br>
|
|||
|
|

HTTP_HOST 请求中的主机名</p>
|
|||
|
|
<p>其中只需要找能够控制的，就可以用来传入参数了</p>
|
|||
|
|
<p>然后又使用<strong>extract</strong>来混淆变量</p>
|
|||
|
|
<p>extract — 从数组中将变量导入到当前的符号表</p>
|
|||
|
|
<div class=highlight><pre><span></span><span class=o><?</span><span class=n>php</span>
