Doc Text:
A flaw was found in the solaris_zone module from the Ansible Community modules. When setting the name for the zone on the Solaris host, the zone name is checked by listing the process with the 'ps' bare command on the remote machine. An attacker could take advantage of this flaw by crafting the name of the zone and executing arbitrary commands in the remote host.

Description Borja Tarraso 2019-11-26 15:49:57 UTC
Vulnerability in solaris_zone from Ansible modules accepts the zone name to perform actions related to zones. However, while running these actions on the system, solaris_zone module check the status of the zone by executing a os.system() call and using the zone name as a parameter. A malicious user could provide a crafted zone name which allows executing commands into the server manipulating the module behaviour.

Currently, there is no mitigation for this issue.

Comment 11 Borja Tarraso 2020-01-02 14:04:14 UTC

Because a flaw exploit would depend on the use of Solaris and Red Hat does not support RHOSP on Solaris, the RHOSP Ansible package will not be updated at this time.

Ansible Engine 2.7.15, 2.8.7, and 2.9.2 as well as previous versions are affected.

Red Hat CloudForms 5.10 (4.7) and 5.11 (5.0) do not ship `ansible` package, it is provided by the official Ansible repository.
