Red Hat Network (RHN) Satellite provides a solution to organizations requiring absolute control over and privacy of the maintenance and package deployment of their servers. It allows organizations to utilize the benefits of the Red Hat Network without having to provide public Internet access to their servers or other client systems. Multiple cross-site scripting (XSS) flaws were found in the RHN Satellite web interface. A remote attacker could use these flaws to perform a cross-site scripting attack against victims using the RHN Satellite web interface.
