WordPress Plugin Vulnerabilities
Popup Builder < 4.0.7 - LFI to RCE
Description
The plugin does not validate and sanitise the sgpb_type parameter before using it in a require statement, leading to a Local File Inclusion issue. Furthermore, since the beginning of the string can be controlled, the issue can lead to RCE vulnerability via wrappers such as PHAR
Proof of Concept
Create a zip archive with a Popup.php contains PHP code, upload it via a low privilege account (by default author and above can upload files, however the blog may allow subscriber to do so, via a plugin, form etc) https://example.com/index.php?sgpb_type=phar://wp-content/uploads/2021/12/1.zip/
