OVE ID
OVE-20160718-0004
Tested versions
These issues were successfully tested on Add From Server WordPress Plugin version 6.2.
Fix
This issue is resolved in Add From Server version 3.3.2.
Introduction
The Add From Server WordPress Plugin is a quick plugin, which allows you to import media & files into the WordPress uploads manager from (remote) webservers. It was discovered that Add From Server is vulnerabile to Cross-Site Request Forgery. It can be exploited by luring the target user into clicking a specially crafted link or visiting a malicious website (or advertisement). Because of this,
the following attack scenario's could be possible:
- Adding illegal content to the victim's server.
- Adding very large files to the victim's server to exaust the amount of avalible disk space.
Details
When a (media) file is added from the server, the source is not validated. This means that not only files from the localhost can be added, but also from other sources. The affected code is not protected with an anti-Cross-Site Request Forgery token.
The function handle_imports() only removes slashes. The vulnerability exists in the file add-from-server/class.add-from-server.php (line 213). Because slashes are removed, the file that will be uploaded must exist in the server root. For example: www.example.com/largefile.txt
The host and filename will be set in a separate parameter, so no slashes are needed.
Proof of concept
POST /wp-admin/upload.php?page=add-from-server HTTP/1.1

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
