The vulnerability described in CVE-2005-4303 represents a critical sql injection flaw within the ezDatabase 2.1.2 content management system that exposes remote attackers to arbitrary command execution capabilities. This vulnerability specifically targets the index.php script where the db_id parameter is processed without adequate input sanitization or validation mechanisms. The flaw exists in the application's database abstraction layer where user-supplied input directly influences sql query construction, creating an environment where malicious actors can manipulate the underlying database operations through carefully crafted input sequences.
The technical implementation of this vulnerability stems from improper parameter handling within the ezDatabase framework where the db_id parameter is directly interpolated into sql statements without appropriate escaping or parameter binding. This primitive injection pattern allows attackers to inject malicious sql fragments that can alter the intended query execution flow, potentially enabling data extraction, modification, or deletion operations. The vulnerability operates at the application layer and requires no special privileges to exploit, making it particularly dangerous as it can be leveraged from any remote location with network access to the affected system.
From an operational impact perspective, this vulnerability creates severe security implications for systems utilizing ezDatabase 2.1.2 or earlier versions. Successful exploitation could result in complete database compromise, leading to unauthorized data access, data corruption, or unauthorized privilege escalation within the database environment. The vulnerability affects the confidentiality, integrity, and availability of database resources, potentially exposing sensitive information such as user credentials, personal data, or business-critical information stored within the database. Organizations running affected systems face significant risk of data breaches and compliance violations, particularly in regulated environments where data protection standards are paramount.
The vulnerability aligns with CWE-89, which specifically addresses sql injection weaknesses in software applications, and demonstrates characteristics consistent with attack patterns documented in the mitre ATT&CK framework under the technique of command and control through database manipulation. Organizations should prioritize immediate remediation by upgrading to ezDatabase versions that implement proper input validation and parameterized queries. Additional mitigations include implementing web application firewalls, applying input filtering rules, and conducting comprehensive security assessments to identify similar vulnerabilities within the application codebase. The vulnerability highlights the critical importance of secure coding practices and proper input validation in preventing remote code execution through database interfaces.
