CVE-2022-27622Network attack vector

Authenticated access to intranet resources

Published Oct 25, 2022 · Updated May 7, 2025

Server-Side Request Forgery in Synology DiskStation Manager before 7.1-42661 allows remote authenticated users to access intranet resources. The vulnerable locus is Package Center, where an unspecified request-handling path accepts attacker-controlled destinations and causes DSM to issue server-side requests. Access requires an authenticated DSM account; the documented consequence is indirect disclosure of intranet resources without stated integrity or availability impact.
