CVE-2022-3980Network attack vector

Unauthenticated SSRF and code execution via XXE

Published Nov 16, 2022 · Updated Apr 29, 2025

XXE in Sophos Mobile managed on-premises 5.0.0 through 9.7.4 allows remote attackers to trigger SSRF and code execution. The OmaDsServlet endpoint processes crafted XML while permitting external-entity resolution, causing the server to request attacker-chosen resources. No authentication or user interaction is required, and exposure is limited to on-premises deployments where the servlet is reachable.
