      <title>CVE-2021-24171 — WooCommerce Upload Files &lt; 59.4 - Unauthenticated Arbitrary File Upload</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2021-24171</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Unknown WooCommerce Upload Files&lt;/p&gt;
&lt;p&gt;The WooCommerce Upload Files WordPress plugin before 59.4 ran a single sanitization pass to remove blocked extensions such as .php. It was possible to bypass this and upload a file with a PHP extension by embedding a &amp;#34;blocked&amp;#34; extension within another &amp;#34;blocked&amp;#34; extension in the &amp;#34;wcuf_file_name&amp;#34; parameter. It was also possible to perform a double extension attack and upload files to a different location via path traversal using the &amp;#34;wcuf_current_upload_session_id&amp;#34; parameter.&lt;/p&gt;</description>
