CVE-2023-43667Network attack vector

Log forgery via unencoded Manager messages

Published Oct 16, 2023 · Updated Jun 16, 2025

Log injection in Apache InLong Manager 1.4.0 through 1.8.0 allows remote attackers to forge log records through crafted requests. The Manager's Log4j2 pattern writes message text without CRLF encoding, while data-node and cluster testConnection controllers accepted request bodies without validation. Network access to either endpoint is sufficient, and forged entries can obscure auditing and malicious-activity tracing.
