CVE-2016-9587

CVSS v2.0

9.3

Critical

VectorAV:N/AC:M/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Ansible versions prior to 2.1.4 Ansible versions prior to 2.2.1
Description The issue is related to improper input validation in Ansible's handling of data sent from client systems. An attacker with control over a client system being managed by Ansible and the ability to send facts back to the Ansible server could use this flaw to execute arbitrary code on the Ansible server using the Ansible server privileges.
Recommendations For versions prior to 2.1.4, update to version 2.1.4 or later. For versions prior to 2.2.1, update to version 2.2.1 or later. As a temporary workaround, consider restricting the ability of client systems to send facts back to the Ansible server until a patch is applied.
