Summary

A vulnerability was found in Ansible engine 2.x up to 2.8 and Ansible tower 3.x up to 3.5. When a module has an argument_spec with sub parameters marked as no_log, passing an invalid parameter name to the module will cause the task to fail before the no_log options in the sub parameters are processed. As a result, data in the sub parameter fields will not be masked and will be displayed if Ansible is run with increased verbosity and present in the module invocation arguments for the task.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Fuzzing and observing application log data/errors for application mapping
    An attacker sends random, malformed, or otherwise unexpected messages to a target application and observes the application's log or error messages returned. Fuzzing techniques involve sending random or malformed messages to a target and monitoring the target's response. The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash. By observing logs and error messages, the attacker can learn details about the configuration of the target application and might be able to cause the target to disclose sensitive information.

    descriptionThis update for ansible to version 2.9.6 fixes the following issues : Security issues fixed : - CVE-2019-14904: Fixed a vulnerability in solaris_zone module via crafted solaris zone (boo#1157968). - CVE-2019-14905: Fixed an issue where malicious code could craft filename in nxos_file_copy module (boo#1157969). - CVE-2019-14864: Fixed Splunk and Sumologic callback plugins leak sensitive data in logs (boo#1154830). - CVE-2019-14846: Fixed secrets disclosure on logs due to display is hardcoded to DEBUG level (boo#1153452) - CVE-2019-14856: Fixed insufficient fix for CVE-2019-10206 (boo#1154232) - CVE-2019-14858: Fixed data in the sub parameter fields that will not be masked and will be displayed when run with increased verbosity (boo#1154231) - CVE-2019-10206: ansible-playbook -k and ansible cli tools prompt passwords by expanding them from templates as they could contain special characters. Passwords should be wrapped to prevent templates trigger and exposing them. (boo#1142690) - CVE-2019-10217: Fields managing sensitive data should be set as such by no_log feature. Some of these fields in GCP modules are not set properly. service_account_contents() which is common class for all gcp modules is not setting no_log to True. Any sensitive data managed by that function would be leak as an output when running ansible playbooks. (boo#1144453)
