Authenticated local-service access via external XML entities
Published Aug 30, 2022 · Updated Aug 3, 2024
XXE in Trellix Data Loss Prevention Endpoint before 11.9.100 allows remote authenticated users to access otherwise unreachable local services. The DLP Agent's XML parser resolves attacker-controlled external entities from a crafted XML file instead of blocking references outside the document's trust boundary. Exploitation requires low-privileged network access and exposes data reachable through local services without reported write or service-interruption impact.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
