CVE-2013-2056

La operación Inter-Satellite Sync (ISS) en Red Hat Network (RHN) Satellite 5.3, 5.4, y 5.5 no valida adecuadamente la "autenticidad" del cliente, lo que permite a atacantes remotos obtener el contenido de un canal evitando la llamada inicial para la autenticación.

Red Hat Network Satellite is a system management tool for Linux-based infrastructures. It allows for provisioning, monitoring, and remote management of multiple Linux deployments with a single, centralized tool. It was discovered that Red Hat Network Satellite did not fully check the authenticity of a client beyond the initial authentication check during an Inter-Satellite Sync operation. If a remote attacker were to modify the satellite-sync client to skip the initial authentication call, they could obtain all channel content from any Red Hat Network Satellite server that could be reached, even if Inter-Satellite Sync support was disabled.
