CVE-2018-25087

Request-handling crash via null project sanitization

Published Jun 6, 2023 · Updated Jan 7, 2025

Denial of service in project.cgi in Arborator Server allows remote authenticated users to crash request handling via a crafted action. The start function sanitizes project with replace() before deriving it from an action value, so an omitted project leaves None and raises an exception. Exploitation requires low-privileged access from an adjacent network, and the demonstrated consequence is an availability interruption rather than data access or modification.
