CVE-2026-102110: Kiteworks Core missing authentication in setup endpoint

CVE-2026-102110 · Severity: medium · CVSS 5.9 · Published 2026-09-30

Kiteworks Core, a secure file transfer and collaboration appliance, contains an unauthenticated endpoint during its initial setup phase that can be repeatedly triggered by network attackers. An attacker can exploit this during the activation window to repeatedly restart the privileged setup process, disrupting configuration and leaving the system in an incomplete state. This vulnerability only affects appliances during their first-time activation before they are fully configured.

Technical details

An unauthenticated endpoint used in the initial appliance setup does not properly enforce state preconditions, allowing network attackers to repeatedly re-trigger the privileged activation process without credentials. The vulnerability is reachable only during the initial activation window before the appliance is fully configured. This causes denial of service through disruption of the setup process and incomplete configuration.

Affected products

Kiteworks Core before 9.5.1
