A flaw was found in foreman 1.5.1. The remote execution plugin runs commands on hosts over SSH from the Foreman web UI. When a job is submitted that contains HTML tags, the console output shown in the web UI does not escape the output causing any HTML or JavaScript to run in the user's browser. The output of the job is stored, making this a stored XSS vulnerability.

Foreman after 1.1 and before 1.9.0-RC1 does not redirect HTTP requests to HTTPS when the require_ssl setting is set to true, which allows remote attackers to obtain user credentials via a man-in-the-middle attack.

Foreman since version 1.5 is vulnerable to an incorrect authorization check due to which users with user management permission who are assigned to some organization(s) can do all operations granted by these permissions on all administrator user object outside of their scope, such as editing global admin accounts including changing their passwords.
