Red Hat Security Advisory 2013-1284-01 - Puppet allows provisioning, patching, and configuration of clients to be managed and automated. A flaw was found in the way Puppet handled YAML content during Representational State Transfer API calls. An attacker could construct a request containing a crafted YAML payload that would cause the Puppet master to execute arbitrary code. It was found that resource_type requests could be used to cause the Puppet master to load and run Ruby files from anywhere on the file system. In non-default configurations, a local user on the Puppet master server could use this flaw to have arbitrary Ruby code executed with the privileges of the Puppet master.

When making REST api calls, the puppet master takes YAML from an untrusted client, deserializes it, and then calls methods on the resulting object. A YAML payload can be crafted to cause the deserialization to construct an instance of any class available in the ruby process, which allows an attacker to execute code contained in the payload.

A remote attacker could use a specially-crafted payload to execute arbitrary code on the puppet master.
