Detailed vulnerability description
The vulnerability allows a remote user to execute arbitrary code.
The vulnerability exists due to download of code without integrity check in the update package handling in the configuration and updater APIs when processing a user-controlled update-package path. A remote user can upload a crafted zip file, set the updater package path to it, and trigger extraction and installation to execute arbitrary code.
Exploitation requires CONFIGURATION_EDIT and ATTACHMENT_ADD permissions, and the crafted archive is installed into the application root through the updater workflow.
Remediation
Install security update from vendor's website.
