CVE-2013-3567  (opens in a new tab)
CWE-94  (opens in a new tab)

Overview

When making REST api calls, the puppet master takes YAML from an untrusted client, deserializes it, and then calls methods on the resulting object. An attacker may take advantage of this to craft a YAML payload that will cause the deserialization to construct an instance of any class in the ruby process and execute code from the payload.
