The vulnerability identified as CVE-2007-6658 represents a critical SQL injection flaw within the CustomCMS 3.1 Demo application, specifically affecting the admin.php and vars.php components. This security weakness resides in the Console page functionality where user input is improperly sanitized before being incorporated into database queries. The vulnerability manifests through the p parameter which serves as an entry point for malicious actors to inject arbitrary SQL commands into the backend database system.
The technical exploitation of this vulnerability occurs when an attacker manipulates the p parameter value in the Console page to include malicious SQL syntax. The application fails to implement proper input validation or parameterized query construction, allowing the injected SQL code to execute with the privileges of the database user account. This flaw directly maps to CWE-89 which defines SQL injection as the insertion of malicious SQL code into input fields for execution by the database. The vulnerability demonstrates poor input sanitization practices and inadequate query parameterization mechanisms that are fundamental requirements in secure application development.
Operationally, this vulnerability presents severe consequences for systems utilizing CustomCMS 3.1 Demo as it enables remote attackers to gain unauthorized access to sensitive database information. Attackers can potentially extract confidential data, modify database records, create new user accounts, or even escalate privileges within the application environment. The remote nature of the attack means that exploitation does not require physical access to the system, making it particularly dangerous for web-facing applications. This vulnerability aligns with ATT&CK technique T1190 which describes the exploitation of remote services through injection attacks, and T1071.004 which covers application layer protocol manipulation.
The impact of this vulnerability extends beyond simple data theft as it can enable full system compromise through database-level attacks. Successful exploitation allows attackers to bypass application-level security controls and directly interact with the underlying database infrastructure. Organizations running this vulnerable version of CustomCMS face significant risk of data breaches, system integrity compromise, and potential regulatory violations depending on the nature of data stored in the affected database. The vulnerability's classification as a remote code execution vector through database manipulation places it within the high-risk category of security flaws requiring immediate remediation.
Mitigation strategies for this vulnerability must include immediate implementation of input validation and parameterized queries to prevent SQL injection attacks. Organizations should deploy web application firewalls to detect and block malicious SQL injection attempts, while also implementing proper access controls and database user privilege management. The most effective long-term solution involves upgrading to a patched version of CustomCMS that addresses this vulnerability through proper input sanitization and query construction practices. Security teams should also conduct comprehensive code reviews focusing on database interaction patterns and implement automated testing procedures to identify similar vulnerabilities in other application components. Additionally, regular security assessments and penetration testing should be conducted to ensure that similar injection vulnerabilities do not exist in other parts of the application infrastructure.
