CVE-2023-3467

Authenticated nsroot privilege escalation

Published Jul 19, 2023 · Updated Oct 24, 2024

Privilege escalation in NetScaler ADC and NetScaler Gateway before fixed builds allows remote authenticated users to gain nsroot access. The advisory does not disclose the specific authorization-control operation that permits escalation through NSIP or SNIP management interfaces. Authenticated management access is required, and successful exploitation grants root-administrator control over the appliance, enabling confidentiality, integrity, and availability impact.
