"The version of Ansible Tower running on the remote web server is 3.5.x prior to 3.5.4 or 3.6.x prior to 3.6.2. It is,
therefore, affected by multiple vulnerabilities.
- An information disclosure vulnerability exists in the Sumologic and Splunk callback plugins due to Ansible
not respecting the 'no_log' flag. A remote attacker can exploit this via the plugin collectors to
potentially disclose sensitive information. (CVE-2019-14864)
- A flaw exists in RabbitMQ manager with the rabbitmq_enable_manager setting due to the setting exposing the
RabbigMQ manager management interface publicly, which may still have the default admin user active. An
unauthenticated, remote attacker can exploit this by guessing the default admin credentials and gain
access to the system. (CVE-2019-19340)
- An information disclosure vulnerability exists in Ansible Tower backups, due to files in
'/var/backup/tower' being left world-readable while a Tower backup is running. An authenticated, remote
attacker with knowledge of the backup can exploit this by navigating to the '/var/backup/tower' directory
and accessing the files, which includes both the SECRET_KEY, backup files, and every credential stored in
Tower. (CVE-2019-19341)
- An information disclosure vulnerability exists in '/websocket' due to Ansible Tower mishandling passwords
with the '#' character, and partially disclosing plaintext passwords when '/websocket' is requested. An
unauthenticated, remote attacker can exploit this via HTTP to disclose partial passwords, allowing the
attacker to brute force or guess predictable passwords. (CVE-2019-19342)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
