CVE-2006-6378 in BTSaveMySql
Summary
by MITRE
BTSaveMySql 1.2 stores sensitive data under the web root with insufficient access control, which allows remote attackers to obtain configuration and save files via direct requests.

The vulnerability identified as CVE-2006-6378 affects BTSaveMySql version 1.2, a backup utility for mysql databases that operates within web environments. This flaw represents a critical misconfiguration that exposes sensitive system information to unauthorized users through improper access controls. The issue stems from the application's failure to implement proper authorization mechanisms when serving files stored within the web root directory, creating an avenue for attackers to directly access configuration and save files without authentication.
The technical implementation of this vulnerability involves the application's storage of sensitive data within the web server's document root directory structure. When BTSaveMySql 1.2 creates backup files or configuration data, these files are placed in locations that are accessible through standard web requests rather than being stored in protected server directories or secured with proper access controls. This configuration allows remote attackers to construct direct HTTP requests targeting specific file paths within the web root, bypassing any intended access restrictions. The flaw specifically relates to the application's lack of proper file access control mechanisms that should prevent unauthorized retrieval of sensitive information.
From an operational impact perspective, this vulnerability creates significant security risks for systems running the affected software. Attackers can directly obtain database configuration files that often contain database credentials, connection strings, and other sensitive information required for database access. Additionally, backup files may contain complete database dumps or partial data that could be exploited for further attacks. The remote nature of this vulnerability means that attackers do not require physical access to the system or local network connectivity to exploit the flaw, making it particularly dangerous. This exposure can lead to unauthorized data access, database compromise, and potential lateral movement within network environments.
The vulnerability aligns with CWE-275 permissions issues and specifically relates to CWE-532 which addresses information exposure through backup files and CWE-732 which covers incorrect permission assignment. From an attack framework perspective, this vulnerability maps to the initial access and credential access phases of the MITRE ATT&CK framework, where adversaries seek to obtain system credentials and sensitive configuration data. The flaw represents a classic example of poor least privilege implementation and improper access control mechanisms that violate fundamental security principles. Organizations should implement proper file access controls and ensure that sensitive data is stored outside of web-accessible directories to prevent such exposures.
Mitigation strategies for this vulnerability should focus on immediate remediation through proper file placement and access control implementation. The primary solution involves moving configuration and backup files outside of the web root directory structure and implementing proper access controls that restrict file access to authorized users only. Additionally, organizations should implement web application firewalls and access control lists to prevent direct file access attempts. Regular security audits should verify that no sensitive files are stored in web-accessible locations, and application security testing should be conducted to ensure proper implementation of access control mechanisms. System administrators should also implement monitoring for unusual file access patterns that might indicate exploitation attempts.
