EUVD-2024-24642

Comprehensive Technical Analysis of EUVD-2024-24642

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2024-24642 pertains to a "Download of Code Without Integrity Check" issue in Apache Doris. This flaw allows an attacker to execute arbitrary code remotely by exploiting the lack of integrity checks on JDBC driver files used for JDBC catalog creation. The severity of this vulnerability is rated with a CVSS Base Score of 9.8, which is considered critical. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates the following:

• Attack Vector (AV:N): Network
• Attack Complexity (AC:L): Low
• Privileges Required (PR:N): None
• User Interaction (UI:N): None
• Scope (S:U): Unchanged
• Confidentiality (C:H): High
• Integrity (I:H): High
• Availability (A:H): High

This high severity score underscores the critical nature of the vulnerability, which can lead to complete system compromise.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector involves an authorized user creating a JDBC catalog with a malicious driver JAR file. The lack of integrity checks means that any code within the JAR file will be executed without verification. Potential exploitation methods include:

• Remote Code Execution (RCE): An attacker can upload a JAR file containing malicious code, which will be executed during the catalog initialization process.
• Privilege Escalation: If the JDBC catalog creation process runs with elevated privileges, the attacker can gain higher-level access to the system.
• Data Exfiltration: The attacker can include code to exfiltrate sensitive data from the system.

3. Affected Systems and Software Versions

The vulnerability affects Apache Doris versions from 1.2.0 through 2.0.4. Users are advised to upgrade to version 2.0.5 or 2.1.x, which includes the necessary fixes.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Upgrade to a Patched Version: Immediately upgrade to Apache Doris version 2.0.5 or 2.1.x.
• Implement Integrity Checks: Ensure that all JDBC driver files are verified for integrity before use.
• Restrict Access: Limit the number of users authorized to create JDBC catalogs and enforce strict access controls.
• Monitor and Log: Implement robust monitoring and logging to detect any suspicious activities related to JDBC catalog creation.
• Regular Audits: Conduct regular security audits to identify and address potential vulnerabilities.

5. Impact on European Cybersecurity Landscape

The impact of this vulnerability on the European cybersecurity landscape is significant due to the widespread use of Apache Doris in various industries. Organizations relying on Apache Doris for data analytics and processing are at risk of data breaches, unauthorized access, and potential service disruptions. The high CVSS score indicates a critical threat that requires immediate attention from cybersecurity professionals and organizations.

6. Technical Details for Security Professionals
