Local privilege escalation to agent host context
Published Jun 28, 2021 · Updated Aug 3, 2024
Local privilege escalation in Tenable Nessus Agent 8.2.4 and earlier for Windows allows local users to execute binaries as the agent host. Tenable has not disclosed the affected components or the incorrect operations that permit specific Windows executables to inherit the agent host context. Reachability requires an authenticated local administrator session; the documented consequence is limited to execution in that elevated context.
