Executive Summary

This vulnerability exists in Xibo versions 4.3.0 and below, specifically in the CMS Developer menu's Module Templating functionality. Authenticated users who have the permission to add or edit custom modules and templates can exploit this flaw to manipulate Twig filters and execute arbitrary server-side functions as the web server user, leading to Remote Code Execution (RCE).

Impact Analysis

The vulnerability allows an authenticated user with specific permissions to execute arbitrary code on the server hosting the Xibo CMS. This can lead to full compromise of the server, including unauthorized data access, modification, or deletion, disruption of services, and potential use of the server for further attacks.

Mitigation Strategies

Upgrade Xibo CMS to version 4.3.1 or later. Alternatively, apply the patch commits available for versions 4.1 and 4.2 as a workaround to fix the Remote Code Execution vulnerability in the Module Templating functionality.
