CVE-2019-3786

Cloud Foundry BOSH Backup and Restore CLI, all versions prior to 1.5.0, does not check the authenticity of backup scripts in BOSH. A remote authenticated malicious user can modify the metadata file of a Bosh Backup and Restore job to request extra backup files from different jobs upon restore. The exploited hooks in this metadata script were only maintained in the cfcr-etcd-release, so clusters deployed with the BBR job for etcd in this release are vulnerable.

Cloud Foundry BOSH Backup y Restore CLI, todas las versiones anteriores a 1.5.0, no comprueba la identificacióbn de scripts backup en BOSH. Un usuario malicioso autorizado de manera remota puede modificar el archivo de metadatos de una tarea de backup y restauración de Bosh para requerir archivos de copia de seguridad adicionales de distintas tareas en la restauración. Los Hooks (ganchos) aprovechados en este script de metadatos solo se mantuvieron en la versión cfcr-etcd, por lo que los clusters implementados con el trabajo BBR para etcd en esta versión son vulnerables.
