CVE-2025-30067 in Kylin
Summary
by MITRE • 03/27/2025
Improper Control of Generation of Code ('Code Injection') vulnerability in Apache Kylin. If an attacker gets access to Kylin's system or project admin permission, the JDBC connection configuration maybe altered to execute arbitrary code from the remote. You are fine as long as the Kylin's system and project admin access is well protected.
This issue affects Apache Kylin: from 4.0.0 through 5.0.1.
Users are recommended to upgrade to version 5.0.2 or above, which fixes the issue.

The vulnerability in question represents a critical improper control of generation of code weakness that fundamentally compromises the security integrity of Apache Kylin systems. This code injection flaw exists within the JDBC connection configuration management functionality, where insufficient input validation and sanitization allows malicious actors to inject arbitrary code through altered connection parameters. The vulnerability specifically targets administrative privileges within the Kylin platform, making it particularly dangerous as it requires only access to system or project administrator accounts to exploit effectively.
From a technical perspective, this weakness falls under CWE-94, which describes improper control of generation of code, a classification that encompasses situations where user-supplied input is directly used to generate executable code without proper validation or sanitization. The vulnerability manifests when administrators configure JDBC connections, as the system fails to properly validate or sanitize the connection string parameters provided by users with administrative privileges. This allows attackers who have gained access to admin accounts to manipulate configuration settings that ultimately result in arbitrary code execution on the Kylin server.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it enables full remote code execution capabilities within the targeted Apache Kylin environment. Attackers can leverage this weakness to execute malicious commands, potentially leading to data exfiltration, system compromise, or further lateral movement within the network infrastructure. The attack vector specifically requires compromised administrative credentials, making it a privilege-based vulnerability that can be particularly devastating in environments where administrative access controls are insufficiently enforced. This aligns with ATT&CK technique T1078 which covers legitimate credentials and valid accounts as a means of gaining initial access.
The affected versions span from Apache Kylin 4.0.0 through 5.0.1, indicating this vulnerability has persisted across multiple major releases, highlighting potential gaps in security testing and code review processes within the development lifecycle. Organizations running these vulnerable versions face significant risk exposure, as the attack surface remains open for any attacker who can compromise administrative accounts or gain unauthorized access to systems with sufficient privileges. The remediation path is straightforward but critical, requiring organizations to upgrade to version 5.0.2 or later, which includes patches specifically designed to address the input validation gaps that enabled this code injection vulnerability.
Organizations should implement comprehensive security measures beyond simple patching, including strict access control policies, regular privilege audits, and monitoring for unusual administrative activities. The vulnerability demonstrates the critical importance of principle of least privilege enforcement and proper input validation mechanisms within enterprise analytics platforms. Security teams must also consider implementing network segmentation and monitoring solutions to detect potential exploitation attempts before they can cause significant damage. This vulnerability serves as a reminder that even seemingly routine administrative functions like database connection configuration can represent major security risks when proper validation controls are absent.
The remediation process should include thorough testing of the patched version in staging environments to ensure compatibility with existing configurations, while also implementing additional security layers such as privileged access management solutions and automated monitoring for suspicious administrative activities. Organizations that cannot immediately upgrade should consider implementing network-based restrictions on Kylin administrative interfaces and enhanced credential protection measures to mitigate the risk exposure during the transition period.
