What the vulnerability does
The Woffice Core plugin for WordPress, used by the Woffice Theme, is vulnerable to arbitrary file uploads due to missing file type validation in the 'saveFeaturedImage' function in all versions up to, and including, 5.4.21. 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.
Explanation of Vulnerability in Simple Terms
Woffice Core versions up to 5.4.21 contain an unrestricted file upload vulnerability. An authenticated user with low privileges can upload arbitrary files to the server without proper validation. This allows attackers to upload malicious code, potentially leading to full site compromise. Update to a version newer than 5.4.21 immediately.
What an attacker can do
Upload arbitrary files (including executable code) to the server and execute them.
Potential impact on your site
Attackers with basic user accounts can run their own code on your site, steal data, or take full control.
Conditions required to exploit
Attacker must have a low-privilege user account on the site.
