mcollective: RCE via YAML deserialization
Published Jun 30, 2017

CRITICALCVSS 3.0
EPSS 2.18%
Description
Versions of MCollective prior to 2.10.4 deserialized YAML from agents without calling safe_load, allowing the potential for arbitrary code execution on the server. The fix for this is to call YAML.safe_load on input. This has been tested in all Puppet-supplied MCollective plugins, but there is a chance that third-party plugins could rely on this insecure behavior.
