The installation script in Katello 1.0 and earlier does not properly generate the Application.config.secrettoken value, which causes each default installation to have the same secret token, and allows remote attackers to authenticate to the CloudForms System Engine web interface as an arbitrary user by creating a cookie using the default secrettoken.
A flaw was found in Katello where the Content View Filter Rules API does not properly enforce authorization on the parent Content View Filter. An authenticated, low-privileged user with Content View permissions in one organization may be able to access and modify filter rules belonging to a Content View Filter in another organization by supplying that filter's identifier. This can result in unauthorized disclosure of filter-rule information and unauthorized changes to unpublished Content View filter configuration.
A potential XSS issue within Foreman / Katello has been reported. It is possible to inject JavaScript code into the Description field of a User and save it. This code is then executed when opening certain pages (e.g., Host Collections).
