An authentication bypass vulnerability has been identified in Foreman when deployed with Gunicorn versions prior to 22.0, due to the puppet-foreman configuration. This issue arises from Apache's modproxy not properly unsetting headers because of restrictions on underscores in HTTP headers, allowing authentication through a malformed header. This flaw impacts all active Satellite deployments (6.13, 6.14 and 6.15) which are using Pulpcore version 4.0+ and could potentially enable unauthorized users to gain administrative access.

An authentication bypass vulnerability exists in Foreman due to Pulpcore when deployed with Gunicorn versions earlier than 22.0. The issue arises from how Apache’s modproxy handles header as it fails to unset it properly due to restrictions on underscores in HTTP headers. This allow authentication through malformed header instead. This flaw affects all Katello/Satellite 6.10+ deployments using Pulpcore from version 4.0+ and could potentially allow unauthorized users to gain admin access.

It is reported by Austin Macdonald that pulp fails to properly remove existing permissions when an object is deleted (e.g. a user account), if an object with the same name is later created it will inherit the previous permissions leading to a potential privilege escalation. Please note that due to the manner in which pulp is used in Satellite6 it is not vulnerable.
