CVE-2022-44621Network attack vector

Unauthenticated command execution via unchecked job ID

Published Dec 30, 2022 · Updated Apr 11, 2025

Command injection in Apache Kylin 4.0.2 and earlier allows remote attackers to execute operating-system commands via a crafted HTTP request. The dumpJobDiagnosisInfo endpoint passes its jobId path variable to the diagnostic service without ParameterFilter validation. No authentication is required, and successful exploitation runs commands with the Kylin server process privileges.
