CVE-2017-20217Public exploitNetwork attack vector

Unauthenticated information disclosure via Configuration REST API

Published Mar 15, 2026 · Updated Mar 15, 2026

Information disclosure in Serviio Pro 1.8 allows remote attackers to read configuration data through its REST API. The Configuration REST API serves unauthenticated GET requests to /rest/import-export/online, /rest/list-folders, and /rest/remote-access, exposing feed URLs, directory names, and the MediaBrowser password. Network reachability to the console service on port 23423 is sufficient; no credentials or user interaction are required.
