CVE-2020-10698

A flaw was found in Ansible Tower when running jobs. This flaw allows an attacker to access the stdout of the executed jobs which are run from other organizations. Some sensible data can be disclosed. However, critical data should not be disclosed, as it should be protected by the no_log flag when debugging is enabled.

Mitigation

This issue is possible to mitigate by disabling the stdout from jobs run through the nginx configuration file. However this may affect the usage of Tower as stdout stream would be hidden. To disable the output of running jobs the entire 'location /websocket' block from the nginx configuration (and restarting nginx service) it would be required. Nginx will stop serving /websocket by 404 HTTP code return.
