The vulnerability identified as CVE-2005-4641 represents a critical SQL injection flaw within the eazyCMS 2.0 content management system, specifically affecting the home.php script. This vulnerability resides in the handling of user-supplied input through the page_id parameter, which is processed without adequate sanitization or validation mechanisms. The flaw enables malicious actors to inject arbitrary SQL commands into the database query execution flow, potentially compromising the entire database infrastructure underlying the CMS. Such vulnerabilities are particularly dangerous because they can be exploited remotely without requiring authentication, making them attractive targets for automated attacks and widespread exploitation.
The technical nature of this vulnerability aligns with CWE-89, which categorizes SQL injection as a fundamental weakness in database query construction where untrusted data is directly incorporated into SQL commands without proper escaping or parameterization. The attack vector specifically targets the page_id parameter in home.php, suggesting that the application constructs SQL queries by concatenating user input directly into the query string rather than utilizing prepared statements or parameterized queries. This primitive approach to database interaction creates an exploitable condition where attackers can manipulate the SQL execution context through carefully crafted input that alters the intended query structure and potentially executes unauthorized database operations.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable complete database compromise including unauthorized data modification, deletion, or extraction of sensitive information. Attackers could leverage this vulnerability to escalate privileges within the CMS, gain access to administrative functions, or even establish persistent backdoors within the web application. The remote execution capability means that attackers do not need physical access to the system or knowledge of internal network configurations to exploit this weakness, making it particularly dangerous in publicly accessible web environments. This vulnerability also aligns with ATT&CK technique T1190, which describes the exploitation of remote services through injection attacks, and T1071.004, covering application layer protocol manipulation.
Mitigation strategies for CVE-2005-4641 should prioritize immediate implementation of input validation and parameterized query construction throughout the eazyCMS codebase. The most effective remediation involves replacing direct string concatenation of user input with prepared statements or parameterized queries that separate SQL command structure from data. Additionally, comprehensive input sanitization should be implemented to filter or escape special characters that could alter SQL command semantics. Organizations should also implement proper access controls and database user permissions to limit the impact of successful exploitation, ensuring that database accounts used by the web application have minimal required privileges. The vulnerability highlights the importance of secure coding practices and proper code review processes, particularly for legacy applications that may not have been designed with modern security considerations in mind. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other components of the web application infrastructure.
