CVE-2025-9909

A flaw was found in the Red Hat Ansible Automation Platform Gateway route creation component. This vulnerability allows credential theft via the creation of misleading routes using a double-slash (//) prefix in the gateway_path. A malicious or socially engineered administrator can configure a honey-pot route to intercept and exfiltrate user credentials, potentially maintaining persistent access or creating a backdoor even after their permissions are revoked.

Weakness

The product defines policy namespaces and makes authorization decisions based on the assumption that a URL is canonical. This can allow a non-canonical URL to bypass the authorization.

Affected Software

Extended Description

If an application defines policy namespaces and makes authorization decisions based on the URL, but it does not require or convert to a canonical URL before making the authorization decision, then it opens the application to attack. For example, if the application only wants to allow access to http://www.example.com/mypage, then the attacker might be able to bypass this restriction using equivalent URLs such as:

Therefore it is important to specify access control policy that is based on the path information in some canonical form with all alternate encodings rejected (which can be accomplished by a default deny rule).
