Technical description

Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to version 1.0.8.6, a flawed central path sanitizer lets an authenticated admin-panel user who holds backup access (default role site_admin or higher) read and delete arbitrary files on a server. An attacker can recover database credentials from config/db.php, read host files such as /etc/passwd, and delete config/db.php to push a site back into install mode for a full takeover. This issue has been patched in version 1.0.8.6.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
