⚡ A crafty twist in the Xibo CMS could let sneaky users execute code on your server—without breaking a sweat! 🔥 Picture a restaurant where the kitchen staff can secretly change the menu without the chef’s approval. In this case, some users have access to modify templates that could lead to unauthorized server commands—yikes! An attacker with the right permissions could manipulate Twig filters to run any command they want as the server's own user. This means they could potentially access sensitive data, modify content, or even take over the entire application—absolutely devastating!
Picture a restaurant where the kitchen staff can secretly change the menu without the chef’s approval. In this case, some users have access to modify templates that could lead to unauthorized server commands—yikes! This vulnerability allows authenticated users with specific permissions to execute arbitrary server-side functions through the Module Templating functionality in the Developer menu, leading to a full remote code execution scenario.
