An input validation flaw was found in the way CloudForms regular expressions were passed to the expression engine via both the JSON API and the web based UI. A user with the ability to view collections and filter them could use this flaw to execute arbitrary shell commands on the host with the privileges of the CloudForms process.

Description Adam Mariš 2016-09-12 07:24:40 UTC 
In ManageIQ product there was found an improper input validation vulnerability in expression engine allowing to trigger code execution. The issue was found to be exploitable both via JSON API, which can be triggered by users authorized with GET/read access to a collection in API, and via UI when filtering on VMs based on regular expression, which can be triggered by users able to view and filter on VMs in UI.
