In the module "SoNice Retour" (sonice_retour) up to version 2.1.0 from Common-Services for PrestaShop, a guest can download personal information without restriction by performing a path traversal attack. Due to a lack of permissions control and a lack of control in the path name construction, a guest can perform a path traversal to view all files on the information system.
