CVE-2026-102123: Kiteworks Core Path Traversal
A Kiteworks appliance setup interface did not confine a user-supplied file path to its intended directory, which could allow an unauthenticated attacker to write a file to any location writable by the affected service account, potentially compromising the integrity of the appliance or rendering it unavailable until an operator intervenes. Exploitation requires network access to the affected interface, which is not reachable on a fully configured appliance in its default configuration; reaching it depends on either the transient window while an appliance is first being provisioned or a non-default appliance configuration.

Event History
Frequently Asked Questions
Which deployments are exposed to this issue?
A fully configured appliance in its default configuration does not expose the affected setup interface. Exposure is limited to appliances during the initial provisioning window or appliances configured to make that interface reachable.
What does an attacker need to exploit it?
An attacker needs network access to the affected setup interface. No authentication or user interaction is required, but exploitation has high attack complexity.
What could successful exploitation allow?
An attacker could write a file to any location writable by the affected service account. This could compromise appliance integrity or make the appliance unavailable until an operator intervenes.
