CVE-2026-102123: Kiteworks Core path traversal in setup interface

CVE-2026-102123 · Severity: high · CVSS 7.4 · Published 2026-09-30

Kiteworks Core, a file transfer and governance appliance, contains a path traversal vulnerability in its setup interface that allows unauthenticated attackers to write files to arbitrary locations on the system. An attacker could compromise the appliance's integrity or cause it to become unavailable. The vulnerability is only exploitable during initial appliance provisioning or with non-default configurations, limiting its practical attack surface.

Technologies: Kiteworks Core. Vendors: Kiteworks.

Technical details

The setup interface fails to properly restrict user-supplied file paths to their intended directory, allowing path traversal (CWE-22) to write files anywhere the service account can write. Exploitation requires network access to the setup interface and does not require authentication, privileges, or user interaction; however, the interface is typically unreachable on fully configured appliances due to access restrictions during normal operation. A successful exploit can modify or delete critical files, compromising appliance integrity or availability.
