CVE-2022-37313Public exploitNetwork attack vector

Internal-service probing via incomplete DNS validation

Published Dec 26, 2022 · Updated Apr 14, 2025

Server-side request forgery in OX App Suite 7.10.6 and earlier allows remote authenticated users to probe internal services via crafted URLs. The backend deny-list validates only the first A or AAAA answer for an attacker-controlled domain, while a later unchecked address can be used for the server request. Exploitation requires a logged-in user who can configure an external mail account or data feed; responses expose internal address and service presence but not service data.
