Descriptions

Unrestricted Upload of File with Dangerous Type vulnerability in NotFound Smallerik File Browser allows Upload a Web Shell to a Web Server. This issue affects Smallerik File Browser: from n/a through 1.1.

The Smallerik File Browser plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to, and including, 1.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
