CVE-2016-9587
CVSS v2.0
9.3
Critical
| Vector | AV: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.
