CVE-2017-7466
Ansible before version 2.3 has an input validation vulnerability in the handling of data sent from client systems.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Ansible before version 2.3 has an input validation vulnerability in the 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.
