What an attacker can do

A low-privileged authenticated backend user can 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. Vendor/CNA’s CVSS 4.0 assessment (base score 9.4/10) rates confidentiality, integrity and availability impact as high.
