CVE-2025-57754

Comprehensive Technical Analysis of CVE-2025-57754

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-57754

Description: The vulnerability affects the eslint-ban-moment plugin, specifically versions 3.0.0 and earlier. The issue arises from the exposure of a sensitive Supabase URI in the .env file. This URI contains embedded credentials (username and password), which, if accessed by an unauthorized party, could grant complete control over the database and user data.

CVSS Score: 9.8

Severity Evaluation: A CVSS score of 9.8 indicates a critical vulnerability. The high score is due to the potential for complete unauthorized access, leading to data exfiltration, modification, or deletion. This vulnerability poses a significant risk to the confidentiality, integrity, and availability of the affected systems.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Environment File Exposure: An attacker could gain access to the .env file through various means, such as unsecured file storage, misconfigured access controls, or inadvertent exposure in version control systems.
2. Supply Chain Attack: If the .env file is included in a public repository or shared with third parties, it could be accessed by malicious actors.
3. Internal Threats: Insiders with access to the development environment could exploit this vulnerability.

Exploitation Methods:

1. Credential Harvesting: Once the .env file is accessed, the attacker can extract the Supabase URI and use the embedded credentials to access the database.
2. Data Exfiltration: The attacker can exfiltrate sensitive data from the database.
3. Data Modification: The attacker can modify database entries, leading to data integrity issues.
4. Data Deletion: The attacker can delete data, causing data loss and potential service disruption.

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 the Supabase URI in the .env file.

4. Recommended Mitigation Strategies

1. Immediate Patching:

   • Upgrade to a version of eslint-ban-moment that addresses this vulnerability.
   • Ensure that the .env file does not contain sensitive information or is adequately secured.

2. Environment Variable Management:

   • Use secure methods to manage environment variables, such as encrypted storage solutions.
   • Avoid committing .env files to version control systems.

3. Access Controls:

   • Implement strict access controls to limit who can view or modify environment files.
   • Use role-based access control (RBAC) to restrict access to sensitive data.

4. Monitoring and Logging:

   • Implement monitoring and logging to detect unauthorized access attempts.
   • Regularly review logs for suspicious activities.

5. Regular Audits:

   • Conduct regular security audits to identify and mitigate similar vulnerabilities.
   • Ensure that all sensitive data is properly secured and access is monitored.

5. Impact on Cybersecurity Landscape

Immediate Impact:

• Organizations using the affected plugin are at high risk of data breaches, leading to potential financial and reputational damage.
• The vulnerability highlights the importance of secure environment variable management.

Long-Term Impact:

• Increased awareness of the risks associated with storing sensitive information in environment files.
• Potential shift towards more secure practices for managing configuration data.
• Emphasis on regular security audits and continuous monitoring.

6. Technical Details for Security Professionals

Vulnerability Details:

• The vulnerability is due to the improper handling of sensitive data in the .env file.
• The Supabase URI contains embedded credentials, which, if exposed, can be used to gain unauthorized access.

Detection Methods:

• Static Analysis: Use static analysis tools to scan for sensitive data in environment files.
• Code Review: Conduct thorough code reviews to identify and mitigate similar issues.
• Security Tools: Implement security tools that can detect and alert on unauthorized access attempts to environment files.

Mitigation Steps:

1. Secure Storage:

   • Use secure storage solutions for environment variables, such as AWS Secrets Manager or Azure Key Vault.
   • Encrypt sensitive data at rest and in transit.

2. Access Control:

   • Implement least privilege access controls.
   • Regularly review and update access permissions.

3. Incident Response:

   • Develop and maintain an incident response plan to quickly address any unauthorized access.
   • Ensure that all stakeholders are aware of the response procedures.

Conclusion: CVE-2025-57754 is a critical vulnerability that underscores the importance of secure environment variable management. Organizations must take immediate action to mitigate this risk and implement robust security practices to prevent similar issues in the future. Regular audits, secure storage solutions, and strict access controls are essential in maintaining a strong security posture.
