CVE-2009-4766 in MS-Pro Portal Scripti
Summary
by MITRE
YP Portal MS-Pro Surumu (aka MS-Pro Portal Scripti) 1.0 and 1.2 stores sensitive information under the web root with insufficient access control, which allows remote attackers to download a database via a direct request for galeri/database/db.mdb.

The vulnerability identified as CVE-2009-4766 affects the YP Portal MS-Pro Surumu (also known as MS-Pro Portal Scripti) versions 1.0 and 1.2. This represents a critical security flaw that stems from improper configuration and access control mechanisms within the web application's file structure. The vulnerability specifically targets the application's handling of sensitive database files, creating an exploitable condition that allows unauthorized remote access to critical system data.
The technical flaw manifests through the insecure placement of database files within the web root directory structure. In this case, the database file named db.mdb is stored in a location that is directly accessible via web requests, without proper authentication or authorization checks. This configuration violates fundamental security principles of least privilege and proper access control. The database file contains sensitive information including user credentials, application data, and potentially business-critical information that should never be directly exposed to unauthenticated users. This vulnerability aligns with CWE-275 permissions issues and specifically represents a case of insufficient access control as defined in the CWE taxonomy.
The operational impact of this vulnerability is severe and multifaceted. Remote attackers can directly access and download the database file through simple HTTP requests, bypassing all intended security measures. This unauthorized access provides attackers with complete read access to the database contents, potentially exposing personal information, login credentials, and other sensitive data. The implications extend beyond immediate data theft to include potential system compromise, as database contents often contain information that can be used for further attacks or social engineering efforts. This vulnerability directly maps to attack techniques described in the MITRE ATT&CK framework under the T1078 credential access and T1041 exfiltration tactics.
Mitigation strategies for this vulnerability should focus on immediate remediation of the file access control configuration. The primary fix involves moving database files outside the web root directory and implementing proper access controls that require authentication and authorization before any database access is granted. Additionally, administrators should implement proper file permissions, ensure that sensitive files are not directly accessible via web requests, and consider implementing web application firewalls to monitor and block suspicious direct database access attempts. Regular security audits should verify that no sensitive files remain accessible through web paths, and the principle of least privilege should be strictly enforced throughout the application's file structure. Organizations should also implement proper logging and monitoring to detect unauthorized access attempts to sensitive files, as this vulnerability could serve as a stepping stone for more sophisticated attacks targeting the broader system infrastructure.
