Security readout for executives and security teams
Plain-English summary
This issue affects Apache Hive when the separate HPL/SQL command-line tool downloads files using COPY FROM FTP. A malicious or compromised FTP server could cause a downloaded file to be written somewhere unintended on the cluster host running the command.
Executive priority
Treat this as a targeted operational risk, not a broad internet-wide emergency. Prioritize validation in data clusters that use HPL/SQL FTP ingestion or rely on external FTP sources.
Technical view
Apache Hive 2.1.0 through 2.3.2 HPL/SQL FTP client code does not verify the destination path for COPY FROM FTP downloads. The source states Hive CLI and HiveServer2 users are not affected because HPL/SQL is invoked separately.
Likely exposure
Exposure is limited to environments running Apache Hive 2.1.0 through 2.3.2 where HPL/SQL is used and COPY FROM FTP contacts FTP servers that could be malicious or compromised.
Exploitation context
The provided sources do not show active exploitation, KEV listing, public exploit tooling, or a CVSS score. Exploitation requires the vulnerable HPL/SQL workflow and control or compromise of the FTP server involved.
Researcher notes
Key evidence gaps are CVSS, CWE mapping, and named fixed versions in the provided bundle. The vulnerability boundary is important: HPL/SQL COPY FROM FTP is in scope; Hive CLI and HiveServer2-only users are stated as unaffected.
Mitigation direction
- Identify Apache Hive deployments running versions 2.1.0 through 2.3.2.
- Disable or restrict HPL/SQL COPY FROM FTP where it is not required.
- Permit FTP downloads only from trusted, controlled servers.
- Limit filesystem permissions for accounts running HPL/SQL jobs.
- Check Apache or distribution vendor guidance for confirmed fixed packages.
Validation and detection
- Inventory Hive versions and confirm whether HPL/SQL is installed or used.
- Review job scripts for COPY FROM FTP usage.
- Check outbound FTP connections from Hive cluster hosts.
- Review file permissions for accounts executing hplsql.
- Confirm Hive CLI and HiveServer2-only workflows are not misclassified as exposed.
