CVE-2023-31103Network attack vector

Unauthenticated cluster modification via mutable identity fields

Published May 22, 2023 · Updated Oct 11, 2024

Improper resource exposure in Apache InLong Manager 1.4.0 through 1.6.0 allows remote attackers to change cluster names and types. Manager update paths accept attacker-controlled cluster and data-node name and type fields and persist changes without enforcing their immutability. The published network vector requires no authentication or user interaction; exploitation changes stored configuration without reported disclosure or service interruption.
