Description

Improper authorization in the ToolGroupResource and RoleAjax REST/DWR endpoints in dotCMS dotCMS 21.02 through 26.06.22-03 on all platforms allows a low-privileged authenticated backend user to self-assign the administrative layout and self-grant the CMS Administrator role, then achieve remote code execution via a crafted OSGi bundle upload whose BundleActivator executes arbitrary shell commands.
