Description Preview
In cPanel versions prior to 67.9999.103, there exists a security vulnerability (SEC-284) where a user account's backup archive could inadvertently contain all MySQL databases on the server, not just the databases owned by that user. This improper input validation vulnerability (CWE-20) could potentially allow unauthorized access to sensitive data from other user accounts on the same server.
Overview
This vulnerability affects cPanel installations before version 67.9999.103. The issue occurs during the backup process where cPanel incorrectly includes all MySQL databases from the server in a user's backup archive instead of limiting the backup to only databases owned by that specific user. This security flaw could lead to information disclosure, as users could potentially access data they should not have permission to view. The vulnerability is tracked as SEC-284 internally by cPanel and has been categorized as CWE-20 (Improper Input Validation).
Remediation
To address this vulnerability, system administrators should:
- Update cPanel to version 67.9999.103 or later as soon as possible
- Audit any backup archives created prior to the update for potential data leakage
- Consider notifying users if there's evidence that unauthorized database access occurred
- Review backup permissions and configurations after updating to ensure they're properly restricted
- Implement additional access controls for backup archives as an extra security measure
