Critical 0-day on a WordPress Plugin Under Active Attack

On May 31, 2021, the Wordfence Threat Intelligence team discovered a critical file upload vulnerability being actively exploited in Fancy Product Designer, a WordPress plugin installed on over 17,000 sites.

As this is a Critical 0-day under active attack and is exploitable in some configurations even if the plugin has been deactivated, we urge anyone using this plugin to update to the latest version available, 4.6.9, immediately.

Fancy Product Designer is a WordPress plugin that offers the ability for customers to upload images and PDF files to be added to products. Unfortunately, while the plugin had some checks in place to prevent malicious files from being uploaded, these checks were insufficient and could easily be bypassed, allowing attackers to upload executable PHP files to any site with the plugin installed. This effectively made it possible for any attacker to achieve Remote Code Execution on an impacted site, allowing full site takeover.

The majority of attacks against this vulnerability are coming from the following IP addresses:

69.12.71.82
92.53.124.123
46.53.253.152
