EUVD-2025-25477

Comprehensive Technical Analysis of EUVD-2025-25477

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-25477 pertains to the eslint-ban-moment plugin, specifically versions 3.0.0 and earlier. The issue involves the exposure of a sensitive Supabase URI in the .env file, which includes embedded credentials (username and password). This exposure can grant an attacker unauthorized access to the database and user data, leading to potential data exfiltration, modification, or deletion.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS:3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high base score indicates a critical vulnerability due to the ease of exploitation (low complexity) and the severe impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Network Access (AV:N): The vulnerability can be exploited remotely over the network.
2. Low Complexity (AC:L): The attack does not require specialized skills or tools.
3. No Privileges Required (PR:N): The attacker does not need any prior privileges.
4. No User Interaction (UI:N): The attack can be executed without any user interaction.

Exploitation Methods:

1. Environment File Exposure: An attacker can gain access to the .env file through various means such as unsecured file storage, misconfigured access controls, or through a compromised system.
2. Credential Harvesting: Once the .env file is accessed, the attacker can extract the Supabase URI, which includes the username and password.
3. Database Access: Using the extracted credentials, the attacker can gain full access to the Supabase database, allowing for data exfiltration, modification, or deletion.

3. Affected Systems and Software Versions

Affected Software:

• eslint-ban-moment plugin versions 3.0.0 and earlier.

Affected Systems:

• Any system or application that uses the eslint-ban-moment plugin and stores sensitive Supabase URIs in the .env file.

4. Recommended Mitigation Strategies

1. Update to the Latest Version: Upgrade to a version of eslint-ban-moment that addresses this vulnerability.
2. Secure Environment Variables: Ensure that sensitive information, such as Supabase URIs, is not stored in plaintext within .env files. Use secure storage solutions and environment variable management practices.
3. Access Controls: Implement strict access controls to limit who can access and modify environment files.
4. Monitoring and Logging: Enable monitoring and logging for access to environment files and database connections to detect any unauthorized access attempts.
5. Regular Audits: Conduct regular security audits to identify and mitigate similar vulnerabilities.

5. Impact on European Cybersecurity Landscape

The exposure of sensitive credentials in environment files is a common issue that can have severe implications for data security and privacy. This vulnerability highlights the importance of secure coding practices and the need for robust security measures in software development. The European cybersecurity landscape must emphasize education and awareness around secure handling of sensitive information to prevent such vulnerabilities from being exploited.
