Winter CMS Local File Inclusion through Server Side Template Injection

Impact

Users with access to backend forms that include a ColorPicker FormWidget can provide a value that would then be included without further processing in the compilation of custom stylesheets via LESS. This had the potential to lead to a Local File Inclusion vulnerability.

By default, only the Brand Settings (backend.manage_branding) and Mail Brand Settings (system.manage_mail_templates) forms both include the colorpicker formwidget and pass the provided value to be compiled in LESS, however it is also common for themes to include it on their Theme Customization (cms.manage_theme_options) form and it is technically possible for the values on that form to also be used in LESS compilation: https://wintercms.com/docs/v1.2/docs/themes/development#asset-compiler-variables.
