CVE-2008-2873 in sHibby sHop
Summary
by MITRE
sHibby sHop 2.2 and earlier stores sensitive information under the web root with insufficient access control, which allows remote attackers to download a database via a direct request to Db/urun.mdb.

The vulnerability identified as CVE-2008-2873 affects sHibby sHop versions 2.2 and earlier, presenting a critical security flaw in web application configuration and access control mechanisms. This issue stems from improper handling of sensitive data within the application's directory structure, where database files are stored with inadequate protection measures. The flaw represents a classic case of insecure direct object reference vulnerability that falls under CWE-22, which specifically addresses improper limitation of a pathname to a restricted directory.
The technical implementation of this vulnerability occurs when the web application fails to enforce proper access controls on database files stored within the web root directory. In this case, the database file named urun.mdb is accessible through a direct URL path Db/urun.mdb without requiring authentication or authorization checks. This misconfiguration allows any remote attacker to craft a simple HTTP request and download the entire database contents, potentially exposing sensitive information including user credentials, personal data, and business-critical information stored within the application's backend.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with a complete database dump that can be used for further exploitation activities. Attackers can leverage this access to perform credential stuffing attacks, extract user accounts, and potentially escalate privileges within the application. The vulnerability directly maps to ATT&CK technique T1213.002 for credential access through data from information repositories, enabling adversaries to harvest sensitive data that may include passwords, personal identification information, and other confidential business data. Additionally, the flaw contributes to broader attack surface expansion by providing unauthorized access to backend data stores that should normally be protected from direct web access.
Mitigation strategies for this vulnerability should focus on implementing proper access control mechanisms and restricting direct file access within web applications. Organizations must ensure that database files and sensitive information are stored outside of the web root directory and that appropriate authentication and authorization checks are enforced before any data access requests are processed. The solution involves implementing proper input validation, enforcing access control policies, and ensuring that all file access requests are properly authenticated and authorized. Security configurations should follow principle of least privilege, where database files are only accessible through secure application interfaces rather than direct web paths. Regular security assessments and code reviews should be conducted to identify similar misconfigurations in web applications, particularly focusing on directory traversal vulnerabilities and improper access controls that could lead to unauthorized data access.
