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.

Mitigation

Whenever is possible, deleting the user from Ansible Tower is the only way to mitigate the authentication of OAuth2 tokens.
