Shelf, plataforma de gestión de inventarios físicos, contiene una vulnerabilidad de Server-Side Request Forgery (SSRF) en versiones anteriores a 1.20.3. Usuarios autenticados con permisos de importación pueden eludir validaciones de URL en la función de importación CSV para ejecutar peticiones HTTP a servidores controlados por atacantes. Afecta principalmente a empresas LATAM que gestionan activos tecnológicos y de infraestructura a través de esta plataforma.
Shelf is a platform for tracking physical assets. Prior to version 1.20.3, authenticated users with the `asset:import` permission can trigger server-side HTTP requests to attacker-controlled URLs through the Asset CSV Content Import feature. The `imageUrl` validation logic can be bypassed through multiple techniques, including image-extension suffixes, image-related path keywords, domain substring matching, and redirect chains. After validation, the server performs an unrestricted `fetch()` request to the supplied URL. This results in a Server-Side Request Forgery (SSRF) vulnerability that allows attackers to reach internal network services, cloud metadata endpoints, and arbitrary external hosts from the application's network context. Additionally, response bodies are fully buffered before size validation, creating a potential memory exhaustion vector. Version 1.20.3 patches the issue.
