CVE-2021-28830

Local privilege escalation via external artifact search

Published Jun 29, 2021 · Updated Sep 16, 2024

Runtime artifact search in affected TIBCO Spotfire server products allows local users on Windows to execute code with service privileges. The Spotfire Server and Enterprise Runtime for R components search for run-time artifacts outside their installation hierarchy and load attacker-planted software. The attack requires low-privileged local Windows access and yields the affected component's elevated privileges, up to full access at that privilege level.
