Impact
An unrestricted file upload vulnerability allows attackers to upload files with dangerous types, including web shells, into the server’s file system. The flaw can lead to remote code execution for the website’s owner.
Affected Systems
Affected products include the Themify Sidepane WordPress Theme (up to version 1.9.8), Themify Newsy WordPress Theme (up to 1.9.9), Themify Folo WordPress Theme (up to 1.9.6), Themify Edmin WordPress Theme (up to 2.0.0), Bloggie WordPress Theme (up to 2.0.8), Photobox WordPress Theme (up to 2.0.1), Wigi WordPress Theme (up to 2.0.1), Rezo WordPress Theme (up to 1.9.7), and Slide WordPress Theme (up to 1.7.5).
Risk and Exploitability
The CVSS score of 9.9 reflects a high severity due to the potential for executing arbitrary code. The EPSS score of less than 1% shows a low current probability of exploitation, and the vulnerability is not listed in CISA KEV. Attackers can likely exploit the flaw by accessing the theme’s upload interface over the web, without needing privileged account access, and upload a web shell that is then executable on the server.
