Name of the Vulnerable Software and Affected Versions Ansible Tower versions prior to 3.6.4 Ansible Tower versions prior to 3.5.6

Description A security flaw was found in Ansible Tower when requesting an OAuth2 token with an OAuth2 application. Ansible Tower uses the token to provide authentication. This flaw allows an attacker to obtain a refresh token that does not expire. The original token granted to the user still has access to Ansible Tower, which allows any user that can gain access to the token to be fully authenticated to Ansible Tower.

Recommendations For Ansible Tower versions prior to 3.6.4, update to version 3.6.4 or later. For Ansible Tower versions prior to 3.5.6, update to version 3.5.6 or later. As a temporary workaround, consider restricting access to OAuth2 tokens to minimize the risk of exploitation.
