CVE-2017-2292
CriticalSummary
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.
Risk Assessment
The organization may be exposed to remote code execution, which could lead to serious security breaches and data loss.
Recommendation
It is recommended to upgrade MCollective to version 2.10.4 or later and to test all used plugins to ensure they do not rely on insecure behavior.
Original NVD description (English source)
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.
