CVE-2020-10684

Publication date 24 March 2020

Ubuntu priority

Cvss 3 Severity Score

A flaw was found in Ansible Engine, all versions 2.7.x, 2.8.x and 2.9.x prior to 2.7.17, 2.8.9 and 2.9.6 respectively, when using ansible_facts as a subkey of itself and promoting it to a variable when inject is enabled, overwriting the ansible_facts after the clean. An attacker could take advantage of this by altering the ansible_facts, such as ansible_hosts, users and any other key data which would lead into privilege escalation or code injection.

Versions prior to 2.5 did not have RESTRICTED_RESULT_KEYS, making a fix very intrusive and likely infeasible.
