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.

An admin user on Foreman can bypass safe mode in templates and execute arbitrary code via the Report Templates function. When changing the "template" JSON value in the POST request, an attacker can exploit the bind() call in safemode to inject an OS command in the underlying operating system.

A stored Cross-site scripting vulnerability was found in foreman. The Comment section in the Hosts tab has incorrect filtering of user input data. As a result of the attack, an attacker with an existing account on the system can steal another user's session, make requests on behalf of the user, and obtain user credentials.
