CVE-2021-29215Network attack vector

Unauthenticated access to restricted Tez resources

Published Jan 18, 2022 · Updated Aug 3, 2024

Access restriction bypass in the Tez component of HPE Data Fabric allows remote attackers to reach resources blocked by access controls. HPE has not published the affected endpoint, code path, or operation that fails to enforce the restriction. Exploitation requires network reachability to the affected Tez component and needs neither authentication nor user interaction; the precise data and operations exposed remain undisclosed.
