Official description
An authentication bypass vulnerability has been identified in Foreman when deployed with External Authentication, due to the puppet-foreman configuration. This issue arises from Apache's mod_proxy 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) and could potentially enable unauthorized users to gain administrative access.

The underlying weakness: Improper Authentication
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
How developers prevent this class of flaw
- Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: total).
- Record last changed materially (score, affected products, status or references).
