Researcher Yogesh Verma


The Zyrex Popup plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the zx_main_page function in versions up to, and including, 1.0. This makes it possible for authenticated attackers, with administrative privileges, to upload arbitrary files on the affected site's server which may make remote code execution possible.
