<h2 id="overview">Overview</h2>
<p><a href="https://github.com/apache/struts">org.apache.struts:struts2-core</a> is a popular open-source framework for developing web applications in the Java programming language.</p>
<p>Affected versions of this package are vulnerable to Remote Code Execution (RCE). The vulnerability exists due to improper input validation when processing certain tag's attributes. The application performs double evaluation of the code if a developer applied forced OGNL evaluation by using the <code>%{...}</code> syntax. A remote attacker can send a specially crafted request to the application and execute arbitrary code on the target system.</p>
<p>Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.</p>
<h2 id="remediation">Remediation</h2>

<!-- Overview -->
<h2 id="overview">Overview</h2>
<p><a href="https://cwiki.apache.org/confluence/display/WW/Home"><code>org.apache.struts:struts2-core</code></a> is an elegant, extensible framework for building enterprise-ready Java web applications.</p>
<p>Affected versions of the package are vulnerable to Arbitrary Command Execution while uploading files with the Jakarta Multipart parser. This particular vulnerability can be exploited by an attacker by sending a crafted request to upload a file to the vulnerable server that uses a Jakarta-based plugin to process the upload request.</p>
<p>The attacker can then send malicious code in the <code>Content-Type</code>, <code>Content-Disposition</code> or <code>Content-Length</code> HTTP headers, which will then be executed by the vulnerable server. <a href="https://github.com/tengzhangchao/Struts2_045-Poc">A proof of concept</a> that demonstrates the attack scenario is publicly available and the vulnerability is being <a href="https://www.theregister.co.uk/2017/03/09/apache_under_attack_patch_for_zero_day_available/">actively exploited in the wild</a>.</p>
<p>Although maintainers of the open source project immediately patched the vulnerability, Struts servers that have yet to install the update remain under attack by hackers who exploit it to inject commands of their choice.</p>
<p>This attack can be achieved without authentication. To make matters worse, web applications don't necessarily need to successfully upload a malicious file to exploit this vulnerability, as just the presence of the vulnerable Struts library within an application is enough to exploit the vulnerability.</p>
<h2 id="remediation">Remediation</h2>
<p>Upgrade <code>org.apache.struts:struts2-core</code> to version 2.3.32, 2.5.10.1 or higher.</p>

Affected versions of the package are vulnerable to Directory Traversal.</p>
<h2 id="details">Details</h2>
<p>A Directory Traversal attack (also known as path traversal) aims to access files and directories that are stored outside the intended folder. By manipulating files with "dot-dot-slash (../)" sequences and its variations, or by using absolute file paths, it may be possible to access arbitrary files and directories stored on file system, including application source code, configuration, and other critical system files.</p>
<p>Directory Traversal vulnerabilities can be generally divided into two types:</p>
<ul>
<li><strong>Information Disclosure</strong>: Allows the attacker to gain information about the folder structure or read the contents of sensitive files on the system.</li>
</ul>
<p><code>st</code> is a module for serving static files on web pages, and contains a <a href="https://snyk.io/vuln/npm:st:20140206">vulnerability of this type</a>. In our example, we will serve files from the <code>public</code> route.</p>
<p>If an attacker requests the following URL from our server, it will in turn leak the sensitive private key of the root user.</p>
<pre><code>curl http://localhost:8080/public/%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/root/.ssh/id_rsa</code></pre>
<p><strong>Note</strong> <code>%2e</code> is the URL encoded version of <code>.</code> (dot).</p>
<ul>
<li><strong>Writing arbitrary files</strong>: Allows the attacker to create or replace existing files. This type of vulnerability is also known as <code>Zip-Slip</code>. </li>
</ul>
<p>One way to achieve this is by using a malicious <code>zip</code> archive that holds path traversal filenames. When each filename in the zip archive gets concatenated to the target extraction folder, without validation, the final path ends up outside of the target folder. If an executable or a configuration file is overwritten with a file containing malicious code, the problem can turn into an arbitrary code execution issue quite easily.</p>
<p>The following is an example of a <code>zip</code> archive with one benign file and one malicious file. Extracting the malicious file will result in traversing out of the target folder, ending up in <code>/root/.ssh/</code> overwriting the <code>authorized_keys</code> file:</p>
<pre><code>2018-04-15 22:04:29 ..... 19 19 good.txt
2018-04-15 22:04:42 ..... 20 20 ../../../../../../root/.ssh/authorized_keys</code></pre>

<!-- Overview -->
<h2 id="overview">Overview</h2>
<p><a href="http://struts.apache.org/">Apache Struts2</a> is a popular open-source framework for developing web applications in the Java programming language.</p>
<p>Affected versions of this package are vulnerable to Arbitrary Code Execution. An unauthenticated attack may be able to exploit this
When using expression literals or forcing expression in Freemarker tags (see example below) and using request values can lead to RCE attack.</p>
<pre><code class="language-xml"><@s.hidden name="redirectUri" value=redirectUri />
<@s.hidden name="redirectUri" value="${redirectUri}" />
<@s.hidden name="${redirectUri}"/></code></pre>
<p>In both cases a writable property is used in the value attribute and in both cases this is threatened as an expression by Freemarker. Please be aware that using Struts expression evaluation style is safe:</p>
<pre><code><@s.hidden name="redirectUri" value="%{redirectUri}" />
<@s.hidden name="%{redirectUri}"/></code></pre>
<h2 id="remediation">Remediation</h2>
<p>Developers are strongly advised to upgrade their <em>Apache Struts</em> components to version <code>2.3.34</code>, <code>2.5.12</code> or higher.</p>
