Description Adam Mariš 2016-07-18 09:53:03 EDT

A vulnerability in CFME and ManageIQ was found allowing users authorized to product feature known as "Control" or "Policies" to run arbitrary code as root.

Vulnerable code:

https://github.com/ManageIQ/manageiq/blob/fb34cad0c44ae453fa4b81ae1c2c964e67ec1053/app/models/bottleneck_event.rb#L75

The `eval` is being run on a property of MiqEventDefinition table. Usually, this table is filled with stock data on product start-up. The default properties of this table are at

https://github.com/ManageIQ/manageiq/blob/fb34cad0c44ae453fa4b81ae1c2c964e67ec1053/db/fixtures/miq_event_definitions.yml#L18

However, attacker can override any of the default stock values and put his code into the MiqEventDefinition table, which is later `eval`ed.
