AI Analysis

Impact

The vulnerability in Apache Kylin’s QuerySQLBlacklistController allows an unauthorized actor to retrieve the SQL blacklist, which contains private data about blocked queries. This exposure violates confidentiality by revealing internal security policies and potentially sensitive query information.

Affected Systems

Apache Kylin versions 4.x through 5.0.4 are vulnerable. The defect resides in the QuerySQLBlacklistController within the REST API component of Apache Kylin, delivered by the Apache Software Foundation.

Risk and Exploitability

The EPSS score is below 1% and the issue is not listed in CISA KEV, indicating no widely documented exploits. However, the CVSS score of 7.5 denotes high severity. The likely attack vector is a remote request to the public QuerySQLBlacklistController endpoint; anyone who can reach the Kylin service could potentially harvest the blacklist information if the endpoint is not authenticated or authorized.

OpenCVE Recommended Actions

  • Upgrade Apache Kylin to version 5.0.5 or later, which contains the fix for this access control issue.

  • Restrict network access to the Kylin REST API using firewall rules or a VPN so that only trusted hosts can reach the endpoint.
