CVE-2024-30896

Comprehensive Technical Analysis of CVE-2024-30896

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-30896 CVSS Score: 9.1

The vulnerability in InfluxDB OSS 2.x through 2.7.11 allows authorized users with read access to the authorization resource of the default organization to retrieve the administrative operator token. This issue is critical due to the potential for unauthorized access to sensitive administrative functions, leading to a high CVSS score of 9.1. The severity is amplified by the fact that administrative tokens can be used to perform a wide range of actions, including data manipulation and system configuration changes.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Internal Threats: Authorized users with read access to the authorization resource can exploit this vulnerability to escalate their privileges.
• External Threats: If an attacker gains initial access to the system through other means (e.g., phishing, exploiting another vulnerability), they can leverage this flaw to obtain administrative tokens.

Exploitation Methods:

• Token Retrieval: An attacker can use the "influx auth ls" command to list and retrieve raw tokens, including the administrative operator token.
• API Access: The vulnerability allows retrieval of tokens via the API, which can be automated for large-scale attacks.

3. Affected Systems and Software Versions

Affected Versions:

• InfluxDB OSS 2.x through 2.7.11

Unaffected Versions:

• InfluxDB OSS 1.x
• InfluxDB Enterprise
• InfluxDB Cloud
• InfluxDB Cloud Dedicated
• InfluxDB Clustered

Fixed Version:

• InfluxDB 2.8.0

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Upgrade: Upgrade to InfluxDB 2.8.0 or later, which addresses the issue by removing the ability to retrieve tokens from the API.
• Access Control: Restrict read access to the authorization resource of the default organization to only trusted users.
• Monitoring: Implement monitoring and alerting for unusual access patterns to the authorization resource.

Long-Term Mitigation:

• Role-Based Access Control (RBAC): Implement strict RBAC policies to limit access to sensitive resources.
• Regular Audits: Conduct regular security audits to identify and mitigate similar vulnerabilities.
• User Education: Educate users on the importance of secure practices and the risks associated with unauthorized access.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2024-30896 highlights the importance of securing administrative tokens and the potential risks associated with improper access controls. This vulnerability underscores the need for robust security practices in database management systems, particularly those handling sensitive data. The high CVSS score indicates the significant impact this vulnerability can have on organizations relying on InfluxDB for their time-series data management.

6. Technical Details for Security Professionals

Technical Overview:

• Token Storage: The administrative operator token is stored under the default organization, making it accessible to users with read access to the authorization resource.
• Command Exploitation: The "influx auth ls" command can be used to list and retrieve raw tokens, including the administrative operator token.
• API Vulnerability: The API allows retrieval of tokens, which will be addressed in future releases by removing this capability.

Detection and Response:

• Log Analysis: Review logs for unusual access patterns to the authorization resource and the use of the "influx auth ls" command.
• Incident Response: Develop an incident response plan that includes steps for identifying and mitigating unauthorized access to administrative tokens.
• Patch Management: Ensure that all instances of InfluxDB are patched to version 2.8.0 or later to mitigate the risk.

Conclusion: CVE-2024-30896 represents a significant risk to organizations using InfluxDB OSS 2.x through 2.7.11. Immediate mitigation through upgrading to the patched version and implementing strict access controls is crucial. Long-term, organizations should focus on robust security practices and regular audits to prevent similar vulnerabilities from being exploited.
