CVE-2006-3780 in Keyif Portal
Summary
by MITRE
Keyifweb Keyif Portal 2.0 stores sensitive information under the web root with insufficient access control, which allows remote attackers to download a database via a direct request for (1) ANKET/anket.mdb, (2) HABER/keyifweb.mdb, (3) ASP/download.mdb, or (4) SAYAC/aktif.mdb in the database/A9S7G6ASD790 directory.

The vulnerability identified as CVE-2006-3780 represents a critical misconfiguration in Keyifweb Keyif Portal 2.0 that exposes sensitive database files to unauthorized remote access. This flaw resides in the application's improper handling of file permissions and access controls, creating a direct pathway for attackers to obtain confidential information stored in Microsoft Access database files. The vulnerability specifically affects the database/A9S7G6ASD790 directory where multiple database files are stored with insufficient access restrictions, allowing attackers to bypass normal authentication mechanisms through direct HTTP requests.
The technical implementation of this vulnerability stems from the web application's failure to enforce proper access control measures for sensitive files stored within the web root directory. Attackers can directly request specific database files using predictable paths including ANKET/anket.mdb, HABER/keyifweb.mdb, ASP/download.mdb, and SAYAC/aktif.mdb, all located within the database/A9S7G6ASD790 directory structure. This represents a classic case of insecure direct object reference vulnerability where the application provides direct access to internal objects without proper authorization checks, making it vulnerable to enumeration and exploitation by malicious actors.
The operational impact of this vulnerability extends beyond simple data exposure, as the compromised database files likely contain sensitive information including user credentials, application configuration details, and potentially confidential business data. The exposure of these database files creates opportunities for attackers to perform further exploitation including credential theft, data manipulation, and potential lateral movement within the affected network. According to the CWE taxonomy, this vulnerability maps to CWE-22 (Improper Limiting of a Pathname to a Restricted Directory) and CWE-284 (Improper Access Control), both of which are fundamental security weaknesses that can lead to significant compromise of system integrity and confidentiality.
The attack surface for this vulnerability is particularly concerning as it allows remote exploitation without requiring authentication or advanced privileges. Attackers can leverage this flaw through standard web browsing tools or automated scripts to discover and download the exposed database files. This vulnerability aligns with ATT&CK technique T1213.002 (Data from Information Repositories) and T1078 (Valid Accounts) as it enables unauthorized access to database repositories and potentially facilitates account compromise through credential exposure. The lack of access controls in the web root directory creates a persistent threat vector that remains exploitable until proper file permissions and access control mechanisms are implemented.
Mitigation strategies for this vulnerability must focus on implementing proper access controls and restricting direct file access to authorized users only. Organizations should immediately relocate sensitive database files outside of the web root directory and implement proper authentication and authorization mechanisms for database access. The solution involves configuring web server permissions to prevent direct access to database files, implementing proper input validation to prevent path traversal attacks, and establishing robust access control policies that enforce the principle of least privilege. Additionally, regular security audits should be conducted to identify and remediate similar misconfigurations in other web applications and systems within the organization's infrastructure.
