CVE-2020-35214Network attack vector

Storage-state deletion via primitive-operation abuse

Published Dec 16, 2021 · Updated Aug 4, 2024

Improper state deletion in Atomix 3.1.5 allows remote authenticated users to remove ONOS storage state through primitive operations. The public record identifies primitive-operation abuse as the deletion path but does not disclose the specific service, method, or missing validation. Membership as an Atomix node is required; successful exploitation deletes ONOS storage state, with no reported confidentiality impact.
