Detection Guidance

This vulnerability allows unauthenticated attackers to inject arbitrary content into pages and posts on affected websites using the DukaMarket theme up to version 1.3.0.

To detect this vulnerability on your system, you can attempt to inject simple script-related HTML tags or shortcodes into pages or posts and observe if the input is improperly neutralized, resulting in code injection.

Since no official patch or specific detection commands are provided, manual testing by submitting payloads such as <script>alert(1)</script> or shortcode injections in content fields may help identify if the vulnerability exists.

• Use curl or similar tools to POST content with script tags or shortcodes to the affected site endpoints and check the response or rendered page for execution or inclusion of injected content.
• Example curl command to test injection via POST (replace URL and parameters accordingly):

curl -X POST -d 'post_content=<script>alert(1)</script>' https://yourdukamarketwebsite.com/wp-admin/post.php

Monitor the page rendering to see if the script executes or appears unescaped, indicating vulnerability.
