CVE-2019-3752Network attack vector

Unauthenticated data exposure and service interruption via XXE

Published Jul 16, 2021 · Updated Sep 16, 2024

XXE injection in Dell EMC Avamar Server 7.4.1, 7.5.0, 7.5.1, 18.2, and 19.1 allows remote attackers to expose data or interrupt service. The server processes crafted DTDs in XML requests with external-entity resolution enabled, but Dell has not identified the affected endpoint or parser. No authentication or user interaction is required; the documented consequences are information exposure and service interruption, with no integrity impact reported.
