CVE-2019-14905
Description
A vulnerability in Ansible's nxos_file_copy module can be used to copy files to a flash or bootflash on NXOS devices. Malicious code could craft the filename parameter to perform OS command injections. This could result in a loss of confidentiality of the system among other issues.
Statement
Ansible Engine 2.7.15, 2.8.7, and 2.9.2 as well as previous versions are affected.
Red Hat Gluster Storage 3 and Red Hat Ceph Storage 3 no longer maintain their own version of Ansible. Therefore this fix will be consumed directly from core Ansible.
In Red Hat OpenStack Platform, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP ansible package.
Mitigation
There is no mitigation for this issue, the flaw can only be resolved by applying updates.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
