Descriptions

OpenStack Murano before 1.0.3 (liberty) and 2.x before 2.0.1 (mitaka), Murano-dashboard before 1.0.3 (liberty) and 2.x before 2.0.1 (mitaka), and python-muranoclient before 0.7.3 (liberty) and 0.8.x before 0.8.5 (mitaka) improperly use loaders inherited from yaml.Loader when parsing MuranoPL and UI files, which allows remote attackers to create arbitrary Python objects and execute arbitrary code via crafted extended YAML tags in UI definitions in packages.

OpenStack Murano en versiones anteriores a 1.0.3 (liberty) y 2.x en versiones anteriores a 2.0.1 (mitaka), Murano-dashboard en versiones anteriores a 1.0.3 (liberty) y 2.x en versiones anteriores a 2.0.1 (mitaka) y python-muranoclient en versiones anteriores a 0.7.3 (liberty) y 0.8.x en versiones anteriores a 0.8.5 (mitaka) no utiliza correctamente loaders heredados de yaml.Loader cuando se analizan sintácticamente archivos MuranoPL y UI, lo que permite a atacantes remotos crear objetos Python arbitrarios y ejecutar código arbitrario a través de etiquetas YAML extendidas manipuladas en definiciones UI en paquetes.
