CVE-2007-5026 in dBlog
Summary
by MITRE
dBlog CMS, probably 2.0, stores sensitive information under the web root with insufficient access control, which allows remote attackers to download a database containing an admin password hash via a direct request for dblog.mdb.

The vulnerability identified as CVE-2007-5026 affects dBlog CMS version 2.0 and represents a critical security flaw in the application's file access control mechanisms. This issue stems from improper configuration of sensitive data storage locations within the web server's document root directory. The vulnerability specifically impacts the database file dblog.mdb which contains administrative credentials in the form of password hashes, making it a prime target for unauthorized access attempts.
The technical flaw manifests through inadequate access control measures that allow remote attackers to directly request and download the database file without proper authentication or authorization checks. This misconfiguration places sensitive information within the web accessible directory structure where it becomes available to any attacker who can make direct HTTP requests to the application. The vulnerability operates at the application level and exploits weak security practices in file placement and access permissions, creating an attack surface that bypasses normal authentication mechanisms.
The operational impact of this vulnerability is severe as it provides attackers with immediate access to administrative credentials in hash format, enabling them to potentially compromise the entire content management system. Once obtained, these password hashes can be subjected to offline dictionary attacks, brute force attempts, or rainbow table lookups to recover the actual administrative passwords. The vulnerability essentially eliminates the need for any form of authentication to access critical system information, making it particularly dangerous for organizations relying on this CMS for their web presence.
This vulnerability aligns with CWE-275 permissions issues and represents a classic example of insecure direct object references as classified under the MITRE ATT&CK framework. The flaw demonstrates poor security practices in application design where sensitive data is stored in insecure locations without proper access controls. Organizations should implement proper file access controls, ensure sensitive data is stored outside the web root directory, and implement proper authentication mechanisms to prevent unauthorized access. The recommended mitigation includes moving database files outside the web accessible directory, implementing proper access controls, and conducting regular security audits to identify similar misconfigurations in other applications.
