What the vulnerability does
The Multi Step Form plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation via the import functionality in all versions up to, and including, 1.7.25. This makes it possible for authenticated attackers, with Administrator-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
Multi Step Form versions 1.7.25 and earlier allow authenticated administrators to upload files without proper validation. An attacker with admin privileges can upload malicious files to the server, potentially gaining the ability to run their own code on the site. This affects confidentiality, integrity, and availability of the affected installation.
What an attacker can do
Upload malicious files to the server and execute arbitrary code on the site.
Potential impact on your site
A compromised admin account can lead to full site takeover, data theft, and malware installation.
Conditions required to exploit
Attacker must have administrator-level access to the WordPress/CMS installation.
